Humber was a provincial electoral district (riding) in Ontario, Canada.

It was created prior to the 1955 provincial election from parts of the York West and York South ridings.

It was eliminated in 1996, when most of its territory was incorporated into the ridings of Etobicoke Centre and Etobicoke—Lakeshore.

Humber was located in the municipalities of York, Toronto, and Etobicoke.

From 1955 to 1963 it was known as York—Humber and existed mostly on the east side of the Humber River.
