Sastamala (Finnish pronunciation: [ˈsɑstɑˌmɑlɑ]) is a town in Finland, located in the Pirkanmaa region.

Sastamala was created in 2009 when the municipalities of Vammala, Äetsä and Mouhijärvi were merged into a single town.

Today, its neighbouring municipalities are Huittinen, Hämeenkyrö, Ikaalinen, Kankaanpää, Kokemäki, Lavia, Nokia, Punkalaidun, Ulvila, Urjala and Vesilahti.

The coat of arms of Sastamala is the former coat of arms of the now defunct municipality of Karkku, originally approved by the Karkku municipal council on November 26, 1962, and approved for use by the Ministry of the Interior on February 12, 1963.

[8][9] The stone grave with its swords, dating to the 4th century in Ristimäki, Vammala, is reminiscent of the prosperous armed burials of the younger Roman Iron Age (200–400 AD) in coastal areas.

[12][13] Sastamala is located on both sides of the Kokemäki River's watershed in the southwest corner of Pirkanmaa.

One of the biggest themed events is the Old Literature Days (Vanhan kirjallisuuden päivät) in the town center during the summer.

Pukstaavi is a national museum that tells the popular story of a Finnish book on cultural history and social significance.
