Winnipeg South was a provincial electoral division in Manitoba, Canada, which existed on two separate occasions.
Liberal-Progressives John Stewart McDiarmid and Ronald Turner served as cabinet ministers in the administration of Douglas Campbell.
Dufferin Roblin became leader of the Progressive Conservative Party in 1954 and Premier of Manitoba in 1958, and included Gurney Evans in his cabinet.
Lloyd Stinson was Winnipeg South's sole representative from the left, winning election for the socialist Cooperative Commonwealth Federation in both 1949 and 1953.
The constituency was eliminated at the 1958 election, when Manitoba abolished its multi-member seats.
