The Turunmaa-class fast gunboats (Finnish: Turunmaa-luokan tykkivene) was a type of vessel, previously operated by the Finnish Navy in the anti-submarine warfare (ASW) and trade protection roles.

Five hull designs and over thirty propulsion variants were looked at during development.

At the time, the electronics of the vessels, and the propulsion system were state of the art and attracted international attention.

Turunmaa was stripped of armaments and served as a floating machine shop and training ship for Satakunta Polytechnics.

The lead vessel was named after the turuma frigates serving in the Archipelago Fleet in the 18th and 19th centuries.
