ORP Kujawiak was a Polish submarine of the Cold War era, originally the Soviet M-245, one of six Soviet M-class submarines leased to Poland. With a displacement of 283 tons surfaced and 353 tons submerged, its primary armament consisted of four 533 mm torpedoes launched from four internal torpedo tubes. The submarine achieved a surface speed exceeding 15 knots, with a range of 4,500 nautical miles at 8 knots.

Launched on 30 June 1949 at the Sudomekh Shipyard in Leningrad, the submarine was commissioned into the Soviet Navy on 31 October 1949, assigned to the Baltic Fleet. Leased to Poland in 1955, it was commissioned into the Polish Navy on 27 May of that year. Bearing the pennant numbers M-104, P-104, and later 305, the submarine was intensively operated until its decommissioning on 31 December 1966, scuttled as a target ship in the Bay of Puck.
