Tõstamaa is a small borough (Estonian: alevik) in Pärnu municipality, Pärnu County, southwestern Estonia. Tõstamaa has a population of 466 (as of 1 January 2020).

Tõstamaa St. Mary's Lutheran church was built in 1763–1768.

Tõstamaa Manor (German: Testama) was first mentioned in 1553 as Testama, when it belonged to the Bishop of Ösel–Wiek. Later the owners have been the Kursells, Helmersens and Staël von Holsteins. The Early-Classical two-storey main building was built in 1804. During a renovation in 1997, several original painted ceilings were uncovered. The manor was dispossessed in 1919 and since 1921 a local school (Tõstamaa Keskkool) is operating in the main building. The most famous inhabitant of the manor is probably orientalist Alexander von Staël-Holstein, who grew up and spent his childhood at the manor.
