Ayeyarwady Region in the context of "Yangon Region"

Lower Myanmar (Burmese: အောက်မြန်မာပြည်, also called Lower Burma) is a geographic region of Myanmar and includes the low-lying Irrawaddy Delta (Ayeyarwady, Bago and Yangon Regions), as well as coastal regions of the country (Rakhine, Kayin and Mon States and Tanintharyi Region).

In the Burmese language, people originating from Upper Myanmar are typically called a-nya-tha for men and a-nya-thu for women, whereas those from Lower Myanmar are called auk tha (အောက်သား) for men and auk thu for women.

The Andaman Islands (/ˈændəmən/) are an archipelago, made up of 200 islands, in the northeastern Indian Ocean about 130 km (81 mi) southwest off the coasts of Myanmar's Ayeyarwady Region. Together with the Nicobar Islands to their south, the Andamans serve as a maritime boundary between the Bay of Bengal to the west and the Andaman Sea to the east. Most of the islands are part of the Andaman and Nicobar Islands, a Union Territory of India, while the Coco Islands and Preparis Island are part of the Yangon Region of Myanmar.

The Andaman Islands are home to the Andamanese, a group of indigenous people made up of a number of tribes, including the Jarawa and Sentinelese. While some of the islands can be visited with permits, entry to others, including North Sentinel Island, is banned by law. The Sentinelese are generally hostile to visitors and have had little contact with any other people. The Indian government and coast guard protect their right to privacy.

The Irrawaddy River (Burmese: ဧရာဝတီမြစ်, pronounced [ʔèjàwədì mjɪʔ], official romanisation: Ayeyarwady) is the principal river of Myanmar, running through the centre of the country. Myanmar's most important commercial waterway, it is about 1,350 miles (2,170 km) long. Originating from the confluence of the N'mai and Mali rivers, it flows from north to south before emptying through the Irrawaddy Delta in the Ayeyarwady Region into the Andaman Sea. Its drainage basin of about 404,000 square kilometres (156,000 sq mi) covers 61% of the land area of Burma, and contains five of its largest cities.

As early as the sixth century, the river was used for trade and transport, and an extensive network of irrigation canals was developed to support agriculture. The river is still of great importance as the largest commercial waterway of Myanmar. It also provides important ecosystem services to different communities and economic sectors, including agriculture, fisheries, and tourism.

Rakhine State (/rəˈkaɪn/ rə-KYN; Burmese: ရခိုင်ပြည်နယ်, MLCTS: ra.hkuing pranynai, pronounced [jəkʰàiɰ̃ pjìnɛ̀]; Rakhine pronunciation: [ɹəkʰàiɰ̃ pɹènè]), formerly known as Arakan State, is a state in Myanmar (Burma). Situated on the western coast, it is bordered by Chin State to the north, Magway Region, Bago Region and Ayeyarwady Region to the east, the Bay of Bengal to the west and the Chattogram Division of Bangladesh to the northwest. The north–south Arakan Mountains or Rakhine Yoma separate Rakhine State from central Myanmar. Off the coast of Rakhine State there are some fairly large islands such as Ramree, Cheduba and Myingun. Rakhine State has an area of 36,762 square kilometres (14,194 sq mi) and its capital is Sittwe (formerly known as Akyab).

As of November 2025, the Arakan Army which is the armed wing of the ethnic Rakhine, maintains de facto control over approximately 90 percent of the state, including 14 of its 17 townships.

Bago Region (Burmese: ပဲခူးတိုင်းဒေသကြီး, pronounced [bəɡó táɪɰ̃ dèθa̰ dʑí]; formerly Pegu Division and Bago Division) is an administrative region of Myanmar, located in the southern central part of the country. It is bordered by Magway Region and Mandalay Region to the north; Kayin State, Mon State and the Gulf of Martaban to the east; Yangon Region to the south and Ayeyarwady Region and Rakhine State to the west. It is located between 46°45'N and 19°20'N and 94°35'E and 97°10'E. It has a population of 4,867,373 (2014).

S'gaw Karen or S'gaw K'nyaw, commonly known simply as Karen, is a Sino-Tibetan language spoken by the S'gaw Karen people of Myanmar and Thailand. A Karenic branch of the Sino-Tibetan language family, S'gaw Karen is spoken by over 2 million people in Tanintharyi Region, Ayeyarwady Region, Yangon Region, and Bago Region in Myanmar, and about 200,000 in northern and western Thailand along the border near Kayin State. It is written using the S'gaw Karen alphabet, derived from the Burmese script, although a Latin-based script is also in use among the S'gaw Karen in northwestern Thailand. Additionally, the Kwekor script is used in Hlaingbwe Township.

Various divergent dialects are sometimes seen as separate languages: Paku in the northeast, Mopwa (Mobwa) in the northwest, Wewew, and Monnepwa.
