Satakunta (in both Finnish and Swedish, Finnish pronunciation: [ˈs̠ɑt̪ɑˌkun̪t̪ɑ]; historically Satacundia or Satagundia) is a region (maakunta / landskap) of Finland, part of the former Western Finland Province. It borders the regions of Southwest Finland, Pirkanmaa, South Ostrobothnia and Ostrobothnia. The capital city of the region is Pori. The name of the region literally means hundred. The historical province of the same name was a larger area within Finland, covering modern Satakunta as well as much of Pirkanmaa.

Turku (/ˈtʊərkuː/ TOOR-koo; Finnish: [ˈturku] ; Swedish: Åbo, Finland Swedish: [ˈoːbu] ) is a city in Finland and the regional capital of Southwest Finland. It is located on the southwestern coast of the country at the mouth of the River Aura. The population of Turku is approximately 207,000, while the metropolitan area has a population of approximately 317,000. It is the 6th–most populous municipality in Finland, and the third–most populous urban area in the country after Helsinki and Tampere.

Turku is Finland's oldest city. It is not known when Turku was granted city status. Pope Gregory IX first mentioned the town of Aboa in his Bulla in 1229, and this year is now used as the founding year of the city. Turku was the most important city in the eastern part (today's Finland) of the Kingdom of Sweden. After the Finnish War, Finland became an autonomous Grand Duchy of the Russian Empire in 1809, and Turku became the capital of the Grand Duchy. However, Turku lost its status as capital only three years later in 1812, when Tsar Alexander I of Russia decided to move the capital to Helsinki. It was only after the last great fire in 1827 that most government institutions were moved to Helsinki along with the Royal Academy of Turku, founded in 1640, which later became the University of Helsinki, thus consolidating Helsinki's position as the new capital. Turku was Finland's most populous city until the late 1840s and remains the regional capital, an important business and cultural centre, and a port.

The Archipelago Sea (Swedish: Skärgårdshavet, Finnish: Saaristomeri) is a part of the Baltic Sea between the Gulf of Bothnia, the Gulf of Finland and the Sea of Åland, within Finnish territorial waters. By some definitions it contains the largest archipelago in the world by the number of islands, estimated at around 50,000, although many of the islands are very small and tightly clustered.

The larger islands are inhabited and connected by ferries and bridges. Åland, including the largest islands of the region, forms an autonomous region within Finland. The rest of the islands are part of the region of Southwest Finland. The Archipelago Sea is a significant tourist destination.

Pirkanmaa (Finnish: [ˈpirkɑmˌmɑː]; Swedish: Birkaland; Latin: Birkaria), also known as Tampere Region in government documents, is a region of Finland. It borders the regions of Satakunta, South Ostrobothnia, Central Finland, Päijät-Häme, Kanta-Häme and Southwest Finland. Most of the water area in the Kokemäki River watershed is located in the Pirkanmaa region, although Lake Vanajavesi is partly in the Kanta-Häme region. The region got its name from Pirkkala, which in the Middle Ages comprised most of present-day Pirkanmaa. Tampere is the regional center and capital of Pirkanmaa, and at the same time the largest city in the region.

The total population of Pirkanmaa was 529,100 on 30 June 2022, which makes it the second largest among Finland's regions after Uusimaa. The population density is well over twice the Finnish average, and most of its population is largely concentrated in the Tampere metropolitan area.

Uusimaa (Finnish: [ˈuːsimɑː]; Swedish: Nyland, Finland Swedish: [ˈnyːlɑnd]; both lit. 'new land') is a region of Finland. It borders the regions of Southwest Finland, Kanta-Häme, Päijät-Häme, and Kymenlaakso. Finland's capital and largest city, Helsinki, along with the surrounding metropolitan area, are both contained in the region, and Uusimaa is Finland's most populous region. The population of Uusimaa is 1,734,000.

While predominantly Finnish-speaking, Uusimaa has the highest total number of native speakers of Swedish in Finland even at a much lower share than two other regions.

Turku metropolitan area or Turku region (Finnish: Turun seutu, Swedish: Åbo region) is the metropolitan area around the city of Turku in Finland. The joint municipal authority of the Turku city region (Finnish: Turun kaupunkiseutu, Swedish: Åbo stadsregion) consists of six municipalities: Turku, Kaarina, Lieto, Naantali, Raisio and Rusko. The Turku metropolitan area forms a compact, urban-like regional growth centre where people commute from a relatively large area of the Southwest Finland region.

The Turku metropolitan area has a population of about 317,000, making it the third largest region in Finland after Helsinki and Tampere. The terms Turku metropolitan area, Turku region, Turku city region, Greater Turku and the other terms used are not fixed and may vary in different contexts.

Kanta-Häme (Finnish pronunciation: [ˈkɑn̪t̪ɑˌhæme̞(ʔ)]; Swedish: Egentliga Tavastland), sometimes referred to as Tavastia Proper, is a region (Finnish: maakunta, Swedish: landskap) of Finland. It borders the regions of Southwest Finland, Pirkanmaa, Päijät-Häme, and Uusimaa. Before the official adoption of the name Kanta-Häme in 1998, the region was commonly known as Häme.

Hämeenlinna is the largest urban area in the region. There are two other municipalities that have township status: Riihimäki and Forssa.
