King's Highway 11, commonly referred to as Highway 11, is a provincially-maintained highway in the Canadian province of Ontario. At 1,784.9 kilometres (1,109.1 mi), it is the second-longest highway in the province, after Highway 17. Highway 11 begins at Highway 400 in Barrie and arches through northern Ontario to the Ontario–Minnesota border at Rainy River via Thunder Bay; the road continues as Minnesota State Highway 72 across the Baudette–Rainy River International Bridge. North and west of North Bay, Highway 11 forms part of the Trans-Canada Highway and is part of MOM's Way between Thunder Bay and Rainy River.

Ontario Provincial Highway Network
The Provincial Highway Network consists of all the roads in Ontario maintained by the Ministry of Transportation of Ontario (MTO), including those designated as part of the King's Highway, secondary highways, and tertiary roads. Components of the system—comprising 16,900 kilometres (10,500 mi) of roads and 2,880 bridges
—range in scale from Highway 401, the busiest highway in North America, to unpaved forestry and mining access roads. The longest highway is nearly 2,000 kilometres (1,200 mi) long, while the shortest is less than a kilometre. Some roads are unsigned highways, lacking signage to indicate their maintenance by the MTO; these may be remnants of highways that are still under provincial control whose designations were decommissioned, roadway segments left over from realignment projects, or proposed highway corridors.
