Southdale is a provincial electoral division in the Canadian province of Manitoba.

Southdale is bordered on the east by the rural ridings of La Verendrye and Springfield, to the south by Seine River, to the north by Radisson and St. Boniface, and to the west by Riel and St. Vital.

Health and social service work accounts for 14% of Southdale's industry.

From 2003 to 2007, Southdale was the only riding in southeastern Winnipeg to be represented by a Progressive Conservative, following historical breakthroughs by the New Democratic Party of Manitoba (NDP) in surrounding ridings in the 2003 provincial election.

The NDP proceeded to oust incumbent MLA Jack Reimer in the 2007 provincial election, completing their sweep of Southeast Winnipeg.
