South Okanagan was a provincial electoral district in the Canadian province of British Columbia beginning with the election of 1916. Following the 1975 election boundary revisions accompanied the riding's renaming to Okanagan South. The riding was originally part of the Yale riding until 1890, and when first that riding was broken up the Okanagan was in Yale-East (1894–1900), and then in Okanagan (1903–1912). Both South Okanagan and North Okanagan were created in advance of the 1916 election.
