Secondary Highway 502, commonly referred to as Highway 502, is a provincially maintained secondary highway in the Canadian province of Ontario. The highway is 151.7 kilometres (94.3 mi) long, connecting Highway 11 east of Fort Frances with Highway 17 in Dryden, via Highway 594. It also carries the Great River Road designation.

The route was constructed throughout the mid- to late 1970s as a new connection between Highway 11 and Highway 17, known as the Manitou Road. It opened in 1980. Another Highway 502 existed between 1956 and 1973, a short alternative route to Highway 2 near Napanee.

Highway 502 begins at a junction with Highway 11 approximately 30 kilometres (19 mi) east of Fort Frances. It progresses north through an isolated region dominated by the forests, exposed bedrock, rivers, numerous lakes, muskeg and mountains of the Canadian Shield, encountering no communities or significant roads along its 151.7-kilometre (94.3 mi) route; it does provide access to numerous logging and mineral access roads. Highway 502 ends at a junction with Highway 594 approximately 6 kilometres (3.7 mi) west of Dryden and 8 kilometres (5.0 mi) west of Highway 17.
