SS Slamat (or "DSS Slamat", with DSS standing for dubbelschroefstoomschip, "twin-screw steamship") was a Dutch ocean liner of the Rotterdam-based Koninklijke Rotterdamsche Lloyd line. Although she was a turbine steamship, she tended not to be referred to as "TSS". She was built in Vlissingen in the Netherlands in 1924 for liner service between Rotterdam and the Dutch East Indies. In 1940 she was converted into a troop ship. In 1941 she was sunk with great loss of life in the Battle of Greece.
