The Sutjeska class was a class of two diesel-electric submarines built for the Yugoslav Navy during the late 1950s and early 1960s. Built by the Uljanik Shipyard in Pula, the two boats were the first class of submarines to be built in Yugoslavia.

The design was done in Yugoslavia and Soviet sensors (radar and sonar) were used. The ships had a refit in the 1970s with modernised sonar.
