Saanich South is a provincial electoral district for the Legislative Assembly of British Columbia, Canada. It was created by 1990 legislation dividing the previous two-member district of Saanich and the Islands which came into effect for the 1991 B.C. election. Between 1966 and 1991, the riding was dominated by Social Credit, who won every election except for 1972 when the riding was won by the British Columbia Progressive Conservative Party.
