The Conestoga Parkway is a highway in the Waterloo Regional Municipality, Ontario, Canada. It runs north/south through the cities of Kitchener and Waterloo, linking the cities via Highway 8 to the main east/west route, Highway 401. It is also called Highway 85.

Highway 85 is one of the busiest roads in the region. As of 2003 it is undergoing extensive improvements around the woefully inadequate junction with the section of Highway 8 that links it to the 401.
