Rudolf Sieckenius (16 May 1896 – 28 April 1945) was a German Generalmajor during World War II who commanded the 16 Panzer Division during Operation Avalanche (Salerno Landings) in September 1943. Despite his widely acknowledged success, which almost resulted in the Allies being pushed back into the sea, Sieckenius was made a scapegoat and sidelined until his death during the Battle of Berlin, when he commanded a security division ("391 Sicherungs Division").
