Cramahe is a rural township located in Northumberland County in southern Ontario, Canada.

With the opening of harbour facilities in the 1840s and the arrival of the railway in 1840, Colborne became an important service centre for the region.

It was named after Sir John Colborne, Lieutenant Governor of Upper Canada, by Joseph Abbott Keeler in 1829.

At the time of dissolution, Colborne Village had a population of 2,040 over an area of 5.2 square kilometres (2.0 sq mi).

Colborne is the home of the Big Apple, a tourist attraction located along Ontario Highway 401.
