SS Algarve was a Danish cargo steamship that was built in 1921 for DFDS. After Germany invaded Denmark in April 1940 Algarve was transferred to the UK Ministry of War Transport. In 1941 an E-boat sank her with all hands in the North Sea. This was the second DFDS ship to be called Algarve. The first was a cargo steamship that was built in Scotland in 1899, bought by the UK government in 1917 and sunk by a U-boat that same year.
