South Perth is an electoral district of the Legislative Assembly in the Australian state of Western Australia. The district is located in the suburbs immediately south of the Perth CBD.

Although occasionally held by an independent, South Perth has typically been a safe Liberal seat. It has never been won by the Labor Party.

South Perth is made up of affluent waterside areas in Perth's inner south. The district is bounded to the north by the Swan River and to the west and south by the Canning River. A series of roads separates the electorate from neighbouring eastern districts. The seat includes the suburbs of Como, Karawara, Manning, Salter Point, Waterford, as well as parts of the suburbs of Kensington and South Perth.

South Perth was first created for the 1901 state election, largely replacing the abolished seat of Canning, and won by William Gordon. However, Canning was re-created for the 1904 election and South Perth abolished, with Gordon transferring to Canning.
