Pohjaslahti is a village and former municipality of Finland at the time of its existence in the Häme Province, now in the Pirkanmaa region.

Pohjaslahti was the last rural municipality to be created in Finland, which happened in 1941.

A farm named Pohjaslahti was established earlier in the 16th century.

Some settlers in the area were Savonians, whose influence can still be seen in the local dialect, e.g. the usage of the extra loi-syllable in plural nouns (for example ristejä may be pronounced as ristilöitä).

Nowadays, the children attend school in Vilppula and Kotala.
