Shch-307 was a Shchuka-class submarine of the Soviet Navy.

Her keel was laid down by Baltiyskiy Zavod in Leningrad on 6 November 1933.

The submarine took part in the whole Baltic Sea campaigns (1939–45), surviving at the war.

The most prominent action of the submarine was the sinking of the U-144 in 1941.

After the war, she was turned into the floating charging station PZS-5, before being stricken: the conning tower was preserved as a memorial.
