Gustav Walter Heinemann (July 23, 1899 - July 7, 1976) was a German politician. He was Minister for Interior Affairs from 1949 to 1950, Minister for Justice from 1966 to 1969 and Federal President of West Germany from 1969 to 1974. He was famous for being open-minded with respect to the student protests of 1968, and he tried to keep his office as down-to-earth as possible (e.g. when asked whether he loves Germany, he answered that he loves his wife).

His daughter Uta Ranke-Heinemann ran for the German presidency unsuccessfully in 1999.
