Toronto Southeast was an Ontario provincial electoral district that existed from 1914 to 1926.

It occupied an area south of College and Gerrard between University and Logan Ave.

In 1926 there was a major redistribution of Ontario seats which resulted in Toronto Southeast being split between three new ridings: St. George, St. David, and Riverdale.

It continued east along Carlton until it reached Parliament Street.
