The Liberal Federation was a liberal conservative South Australian political party from 1922 to 1932. It came into existence largely as a result of friction between the non-Labor parties in South Australia stemming from the formation of the Country Party in 1919. That led to the Liberal Union, under the leadership of Henry Barwell, transforming into the Liberal Federation. Richard Layton Butler was also a South Australian premier during the party's existence. It was a predecessor to the South Australian Liberal and Country League.
