Timiskaming—Cochrane is a provincial electoral district in northern Ontario, Canada.

In 2005, legislation was passed by the Legislature to divide Ontario into 107 electoral districts, beginning with the next provincial election in 2007.

The eleven northern electoral districts are those defined for federal purposes in 1996, based on the 1991 census (except for a minor boundary adjustment).

Without this legislation, the number of electoral districts in Northern Ontario would have been reduced from eleven to ten.

Included in the riding is the city of Temiskaming Shores and the towns of Cochrane, Iroquois Falls, Kirkland Lake, Larder Lake, McGarry, Englehart, Earlton, Cobalt, West Nipissing, and French River.
