The Balkans (/ˈbɔːlkənz/ BAWL-kənz, /ˈbɒlkənz/ BOL-kənz), corresponding partially with the Balkan Peninsula, is a geographical area in southeastern Europe with various geographical and historical definitions. The region takes its name from the Balkan Mountains that stretch throughout the whole of Bulgaria. The Balkan Peninsula is bordered by the Adriatic Sea in the northwest, the Ionian Sea in the southwest, the Aegean Sea in the south, the Turkish straits in the east, and the Black Sea in the northeast. The northern border of the peninsula is variously defined. The highest point of the Balkans is Musala, 2,925 metres (9,596 ft), in the Rila mountain range, Bulgaria.

The concept of the Balkan Peninsula was created by the German geographer August Zeune in 1808, who mistakenly considered the Balkan Mountains the dominant mountain system of southeastern Europe spanning from the Adriatic Sea to the Black Sea. In the 19th century the term Balkan Peninsula was a synonym for Rumelia, the parts of Europe that were provinces of the Ottoman Empire at the time. It had a geopolitical rather than a geographical definition, which was further promoted during the creation of Yugoslavia in the early 20th century. The definition of the Balkan Peninsula's natural borders does not coincide with the technical definition of a peninsula; hence modern geographers reject the idea of a Balkan Peninsula, while historical scholars usually discuss the Balkans as a region. The term has acquired a stigmatized and pejorative meaning related to the process of Balkanization. The region may alternatively be referred to as Southeast Europe.

Attica (Greek: Αττική, romanised: Attikí, Greek pronunciation: [atiˈci]; Ancient Greek: Ἀττική, romanised: Attikḗ, Ancient Greek pronunciation: [atːikɛ̌ː]), or the Attic Peninsula, is a historical region that encompasses the entire Athens metropolitan area, which consists of the city of Athens, the capital of Greece and the core city of the metropolitan area, as well as its surrounding suburban cities and towns. It is a peninsula projecting into the Aegean Sea, bordering on Boeotia to the north and Megaris to the west. The mines of Laurion were an important mining region located at Lavrio, on the southern tip of the peninsula.

The history of Attica is closely linked with that of Athens. In ancient times, Attica corresponded with the classical Athens city‑state. It was the most prominent region in Ancient Greece, specifically during the Golden Age of Athens in the classical period. Ancient Attica was divided into demoi, or municipalities, from the reform of Cleisthenes in 508/7 BC, grouped into three zones: urban (astu) in the region of Athens main town, and Piraeus (the port), coastal (paralia) along the coastline, and inland (mesogeia) in the interior.

Crimea (/kraɪˈmiːə/ kry-MEE-ə) is a peninsula in Eastern Europe, on the northern coast of the Black Sea, almost entirely surrounded by the Black Sea and the smaller Sea of Azov. The Isthmus of Perekop connects the peninsula to Kherson Oblast in mainland Ukraine. To the east, the Crimean Bridge, constructed in 2018, spans the Strait of Kerch, linking the peninsula with Krasnodar Krai in Russia. The Arabat Spit, located to the northeast, is a narrow strip of land that separates the Syvash lagoons from the Sea of Azov. Across the Black Sea to the west lies Romania and to the south is Turkey. The population is 2.4 million, and the largest city is Sevastopol. The region, internationally recognised as part of Ukraine, has been under Russian occupation since 2014.

Called the Tauric Peninsula until the early modern period, Crimea has historically been at the boundary between the classical world and the steppe. Greeks colonised its southern fringe and were absorbed by the Roman and Byzantine Empires and successor states while remaining culturally Greek. Some cities became trading colonies of Genoa, until conquered by the Ottoman Empire. Throughout this time the interior was occupied by a changing cast of steppe nomads, coming under the control of the Golden Horde in the 13th century from which the Crimean Khanate emerged as a successor state. In the 15th century, the Khanate became a dependency of the Ottoman Empire. Lands controlled by Russia and Poland-Lithuania were often the target of slave raids during this period. In 1783, after the Russo-Turkish War (1768–1774), the Russian Empire annexed Crimea. Crimea's strategic position led to the 1854 Crimean War and many short lived regimes following the 1917 Russian Revolution. When the Bolsheviks secured Crimea, it became an autonomous soviet republic within the Russian Soviet Federative Socialist Republic. It was occupied by Germany during World War II. When the Soviets retook it in 1944, Crimean Tatars were ethnically cleansed and deported under the orders of Joseph Stalin, in what has been described as a cultural genocide. Crimea was downgraded to an oblast in 1945. In 1954, the USSR transferred the oblast to the Ukrainian Soviet Socialist Republic on the 300th anniversary of the Pereyaslav Treaty in 1654.

The Arabian Peninsula (Arabic: شبه الجزيرة العربية, romanized: shibh al-jazīra al-ʿarabiyya, or جزيرة العرب, jazīrat al-ʿarab, 'the Island of Arabs'), or simply Arabia, is a peninsula in West Asia, situated north-east of Africa on the Arabian plate. At 3,237,500 km (1.25 million sq mi), comparable in size to India, the Arabian Peninsula is the largest peninsula in the world.

Geographically, the Arabian Peninsula comprises Bahrain, Kuwait, Oman, Qatar, Saudi Arabia, the United Arab Emirates (UAE) and Yemen, as well as southern Iraq and Jordan. The largest of these is Saudi Arabia. In ancient antiquity, particularly from the 9th century BC to the 7th century AD, the Sinai Peninsula was also considered a part of Arabia.

The Peloponnese, Peloponnesus, or Morea, is a peninsula and geographic region in Southern Greece, and the southernmost region of the Balkans. It is connected to the central part of the country by the Isthmus of Corinth land bridge, which separates the Gulf of Corinth from the Saronic Gulf. From the late Middle Ages until the 19th century, the peninsula was known as the Morea, a name still in colloquial use in its demotic form.

Chalkidiki (/kælˈkɪdɪki/; Greek: Χαλκιδική, romanized: Chalkidikḗ [xalciðiˈci], alternatively Halkidiki), also known as Chalcidice, is a peninsula and regional unit of Greece, part of the region of Central Macedonia, in the geographic region of Macedonia in Northern Greece. The autonomous Mount Athos region constitutes the easternmost part of the peninsula, but not of the regional unit.

The capital of Chalkidiki is the town of Polygyros, located in the centre of the peninsula, while the largest town is Nea Moudania. Chalkidiki is a popular summer tourist destination.

Salento (Italian: [saˈlɛnto]; Salentino: Salentu; Salento Griko: Σαλέντο) is a cultural, historical, and geographic region at the southern end of the administrative region of Apulia, in southern Italy. It is a sub-peninsula of the Italian Peninsula, sometimes described as the "heel" of the Italian "boot". It encompasses the entire administrative area of the Province of Lecce, most of the Province of Brindisi (all of it except Fasano, Ostuni and Cisternino), and the south-eastern part of the Province of Taranto (like Grottaglie and Avetrana, but not Taranto itself).

The Iberian Peninsula (IPA: /aɪˈbɪəriən/ eye-BEER-ee-ən), also known as Iberia, is a peninsula in south-western Europe. Mostly separated from the rest of the European landmass by the Pyrenees, it includes the territories of Peninsular Spain and Continental Portugal, comprising most of the region, as well as the tiny adjuncts of Andorra, Gibraltar, and, pursuant to the traditional definition of the Pyrenees as the peninsula's northeastern boundary, a tiny part of France. With an area of approximately 583,254 square kilometres (225,196 sq mi), and a population of roughly 56 million, it is the second-largest European peninsula by area, after the Scandinavian Peninsula.

The Sinai Peninsula, or simply Sinai (/ˈsaɪnaɪ/ SY-ny; Arabic: سيناء, romanized: Sīnāʾ, Egyptian Arabic: سينا, romanized: Sīna), is a peninsula in Egypt, and the only part of the country located in Asia. It is between the Mediterranean Sea to the north and the Red Sea to the south, and is a land bridge between Asia and Africa. Sinai has a land area of about 60,000 km (23,000 sq mi) (6 percent of Egypt's total area) and a population of approximately 600,000 people. Administratively, the vast majority of the area of the Sinai Peninsula is divided into two governorates: the South Sinai Governorate and the North Sinai Governorate. Three other governorates span the Suez Canal, crossing into African Egypt: Suez Governorate on the southern end of the Suez Canal, Ismailia Governorate in the center, and Port Said Governorate in the north.

In the classical era, the region was known as Arabia Petraea. The peninsula acquired the name Sinai in modern times due to the assumption that a mountain near Saint Catherine's Monastery is the Biblical Mount Sinai. Mount Sinai is one of the most religiously significant places in the Abrahamic faiths.

Messenia (Ancient Greek: Μεσσηνία) was an ancient district of the southwestern Peloponnese, more or less overlapping the modern Messenia region of Greece. It occupied the peninsular region usually called by the same name along with some of the mainland. To the north it had a border with Elis along the Neda river. From there the border with Arcadia ran along the tops of Mount Elaeum and Mount Nomia and then through foothills of Taygetus. The eastern border with Laconia went along the Taygetus ridge up to the Koskaraka river, and then along that river to the sea, near the city of Abia. The Ionian Sea forms the peninsula's western border, and the peninsula and mainland sections enclose the Messenian Gulf to the south.

Ancient Messenia existed continuously without change of name and with little change of territory to the modern Regional Unit of Greece of the same name.

Stagira (/stəˈdʒaɪrə/), Stagirus (/-rəs/), or Stageira (Greek: Στάγειρα or Στάγειρος) was an ancient Greek city located near the eastern coast of the peninsula of Chalkidice, which is now part of the Greek province of Central Macedonia. It is chiefly known for being the birthplace of Aristotle, the Greek philosopher and polymath, student of Plato, and teacher of Alexander the Great. The ruins of the city lie approximately 18 kilometres (11 mi) northeast of the present-day village of Stagira, and adjacent to the town of Olympiada.

The Apennines or Apennine Mountains (/ˈæpənaɪn/ AP-ə-nyne; Italian: Appennini [appenˈniːni]) are a mountain range consisting of parallel smaller chains extending c. 1,200 km (750 mi) the length of peninsular Italy. In the northwest they join the Ligurian Alps at Altare. In the southwest they end at Reggio di Calabria, the coastal city at the tip of the peninsula. Since 2000 the Environment Ministry of Italy, following the recommendations of the Apennines Park of Europe Project, has defined the Apennines System to include the mountains of north Sicily, a total distance of 1,500 kilometres (930 mi). The system forms an arc enclosing the east of the Ligurian and Tyrrhenian seas.

The Apennines conserve some intact ecosystems that have survived human intervention. In these are some of the best-preserved forests and montane grasslands in Europe, now protected by national parks and, within them, a high diversity of flora and fauna. These mountains are one of the last refuges of the big European predators such as the Italian wolf and the Marsican brown bear, now extinct in the rest of Central Europe.

The Izu peninsula (伊豆半島, Izu Hantō; Japanese pronunciation: [i.(d)zɯ, i.(d)zɯ haꜜn.toː]) is a mountainous peninsula with a deeply indented coastline to the west of Tokyo on the Pacific coast of the island of Honshu, Japan, the largest of the four main islands of Japan. Formerly known as Izu Province, Izu peninsula is now a part of Shizuoka Prefecture. The peninsula has an area of 1,421.24 km (548.74 sq mi) and its estimated population in 2005 was 473,942 people. The peninsula's populated areas are located primarily on the north and east.

Korea is a peninsular region in East Asia consisting of the Korean Peninsula, Jeju Island, and smaller islands. Since the end of World War II in Asia in 1945, it has been politically divided at or near the 38th parallel between North Korea (Democratic People's Republic of Korea; DPRK) and South Korea (Republic of Korea; ROK). Both countries proclaimed independence in 1948, and the two countries fought the Korean War from 1950 to 1953. The region is bordered by China to the north and Russia to the northeast, across the Amnok (Yalu) and Duman (Tumen) rivers, and is separated from Japan to the southeast by the Korea Strait.

Known human habitation of the Korean peninsula dates to 40,000 BC. The kingdom of Gojoseon, which according to tradition was founded in 2333 BC, fell to the Han dynasty in 108 BC. It was followed by the Three Kingdoms period, in which Korea was divided into Goguryeo, Baekje, and Silla. In 668 AD, Silla conquered Baekje and Goguryeo with the aid of the Tang dynasty, forming Unified Silla; Balhae succeeded Goguryeo in the north. In the late 9th century, Unified Silla collapsed into three states, beginning the Later Three Kingdoms period. In 918, Goguryeo was resurrected as Goryeo, which achieved what has been called a "true national unification" by Korean historians, as it unified both the Later Three Kingdoms and the ruling class of Balhae after its fall. Goryeo, whose name developed into the modern exonym "Korea", was highly cultured and saw the invention of the first metal movable type. During the 13th century, Goryeo became a vassal state of the Mongol Empire. Goryeo overthrew Mongol rule before falling to a coup led by General Yi Seong-gye, who established the Joseon dynasty in 1392. The first 200 years of Joseon were marked by peace; the Hangul, the Korean alphabet was created and Confucianism became influential. This ended with Japanese and Qing invasions, which brought devastation to Joseon and led to Korean isolationism. After the invasions, an isolated Joseon experienced another nearly 200-year period of peace and prosperity, along with cultural and technological development. In the final years of the 19th century, Japan forced Joseon to open up and Joseon experienced turmoil such as the Kapsin Coup, Donghak Peasant Revolution, and the assassination of Empress Myeongseong. In 1895, Japan defeated China in the First Sino-Japanese War and China lost suzerainty over Korea and Korea was placed under further Japanese influence. In 1897, the centuries old Joseon was replaced by the Korean Empire with the Joseon's last king, Gojong, becoming the Emperor of the Korean Empire. Japan's further victory in the 1904–1905 Russo-Japanese War, expelled Russian influence in Korea and Manchuria. In 1905, the Korean Empire became a protectorate of the Empire of Japan. In 1910, the Empire of Japan officially annexed the Korean peninsula.

The Kamchatka Peninsula (Russian: полуостров Камчатка, romanized: poluostrov Kamchatka, pronounced [pəlʊˈostrəf kɐmˈt͡ɕætkə]) is a 1,250-kilometre-long (777 mi) peninsula in the Russian Far East, with an area of about 270,000 km (100,000 sq mi). The Sea of Okhotsk bounds the peninsula's western coastline, immediately offshore of the peninsula and below the Bering Sea runs the 9,600-metre-deep (31,496 ft) Kuril–Kamchatka Trench. Its eastern coastline is the Bering Sea, part of the Pacific Ocean.

The Kamchatka Peninsula, the Commander Islands, and Karaginsky Island constitute Kamchatka Krai of the Russian Federation. The majority of the 322,079 inhabitants are ethnic Russians, with about 13,000 being Koryaks (2014). More than half of the population lives in Petropavlovsk-Kamchatsky (179,526 in 2010) and nearby Yelizovo (38,980). The Kamchatka Peninsula contains the volcanoes of Kamchatka, a UNESCO World Heritage Site, that form part of the Ring of Fire.

Dejima (Japanese: 出島; lit. 'exit island') or Deshima, in the 17th century also called Tsukishima (築島; lit. 'built island'), was an artificial island off Nagasaki, Japan, that served as a trading post for the Portuguese (1570–1639) and subsequently the Dutch (1641–1858). For 220 years, it was the central conduit for foreign trade and cultural exchange with Japan during the isolationist Edo period (1600–1869), and the only Japanese territory open to Westerners.

Dejima was created in 1636 by digging a canal through a small peninsula and linking it to the mainland with a small bridge. The island was constructed by the Tokugawa shogunate, whose isolationist policies sought to preserve the existing sociopolitical order by forbidding outsiders from entering Japan while prohibiting most Japanese from leaving. Dejima housed European merchants and separated them from Japanese society while still facilitating lucrative trade with the West.
