SS Westfalen was a German ship built in 1906 at J.C. Tecklenborg in Geestemünde. During World War II, the ship was used for transport between Germany and German-occupied Norway. On 7 September 1944 the ship sank off Marstrand, probably hit by a naval mine. Seventy-eight people aboard survived, but most of the locked-up Norwegian prisoners-of-war were casualties, including Petter Moen, Reidar Olaf Østlid and Sverre Lid. SS-Sturmscharführer Wilhelm Heinze also died.
