Leo Raubal (full name: Leo Rudolf Raubal, 12 October 1906 in Linz – 18 August 1977, Spain) was a teacher, soldier and manager. He was a son of Leo Raubal (Sr.) and his wife Angela (Adolf Hitler's half-sister).

Leo Raubal Jr. worked in Salzburg as a teacher of chemistry. He visited his mother sporadically while she was living in Berchtesgaden. According to William Patrick Hitler, Leo did not like his uncle Adolf and he blamed him for the death of his sister Geli. This cannot be confirmed because (according to historian Werner Maser) Leo said in 1967 that Hitler was "absolutely innocent." Leo Raubal was, just like his younger cousin, Heinz Hitler, but unlike William Patrick Hitler, a "favorite nephew of the leader," and Hitler liked to spend his time with him.

Before the war he became a manager of the Linz Steelworks. In October 1939, he was drafted into the Luftwaffe and was a lieutenant in the engineering corps. He looked similar to Adolf Hitler and sometimes served as Hitler's double during the war.
