Pirkanmaa (Finnish: [ˈpirkɑˌmːɑː]; 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 520,532 on 30 September 2020, 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 sub-region.
