The electoral district of South Launceston, sometimes referred to as Launceston South, was an electoral district of the Tasmanian House of Assembly. It was based in Tasmania's second city, Launceston, and the surrounding rural area.
The seat was created as a single-member seat ahead of the 1871 election following the dissolution of the multi-member Launceston seat. In 1886, it became a two-member seat, and at the 1897 election, it was abolished when the Launceston seat was recreated under a trial of the Hare-Clark model.
