Saskatoon Southeast is a provincial electoral district for the Legislative Assembly of Saskatchewan, Canada.

Since a boundary redraw in 2022, it currently encompasses the Saskatoon neighbourhoods of Lakeridge, Briarwood, Lakewood, Rosewood, and a small portion of Lakeview, which it lost to the redistributed riding of Saskatoon Eastview.

This rural territory was moved to Saskatoon Stonebridge-Dakota in 2012, making it again into an entirely urban constituency for the 2016 general election, this time centered in the neighbourhoods of Lakeview, Lakeridge and Rosewood.

In the This district has historically been one of the safest seats for the Saskatchewan Party in Saskatoon, having returned Minister Don Morgan of the Saskatchewan Party to office in every election since the 2003 general election.

It was one of the first three Saskatoon area seats the party won that year since its formation in 1997.
