SS Sołdek was a Polish coal and ore freighter. She was the first ship built in Szczecin (Poland) after World War II and the first seagoing ship completed in Poland. She was the first of 29 ships classed as Project B30, built between 1949 and 1954 in Stocznia Gdańska (Gdańsk Shipyard). The name was given in honour of Stanisław Sołdek, one of the shipyard's shock workers.
The ship is currently preserved as a museum ship in Gdańsk, as a part of National Maritime Museum collection.
