Tobruk was a 7,090 GRT cargo ship which was built in 1941 as Empire Builder by William Gray & Company Ltd for the Ministry of War Transport (MoWT). On completion she was handed over to the Polish government-in-exile (along with four others; Narwik, Bałtyk, Białystok and Borysław, which in 1950 was renamed to Bytom) and renamed Tobruk. She was a member of a number of convoys during the Second World War. She was sold in 1951 to Polskie Linie Oceaniczne and served until 1967. She was scrapped in 1968.
