King's Highway 63, commonly referred to as Highway 63, is a provincially maintained highway in the Canadian province of Ontario. The 63.5-kilometre (39.5 mi) route travels from Highway 11 and Highway 17 (the Trans-Canada Highway) in North Bay northeast to the Ontario-Quebec provincial boundary, where it continues as Route 101 into Témiscaming.

The route was assumed in 1937, following the merger of the Department of Northern Development (DND) into the Department of Highways (DHO), predecessor to the modern Ministry of Transportation of Ontario (MTO). It travelled from what was then Highway 11 (Main Street) in downtown North Bay northeast to its present terminus. The highway follows the same route today, with the exception of the westernmost 1.9 kilometres (1.2 mi), which were transferred to the City of North Bay in 1998.
