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

It occupied an area north of College and Gerrard between Lansdowne and Spadina.

In 1926 there was a major redistribution of Ontario seats which resulted in Toronto Northwest being split between five new ridings called from west to east, Brockton, Dovercourt, Bellwoods, St. Andrew, and St. Patrick.

It bordered College Street, Lansdowne Avenue on the west, Spadina Avenue on the east and the city limits to the north.
