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, following 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 (as well as for a short distance through Orillia), Highway 11 forms part of the Trans-Canada Highway. The highway is also part of MOM's Way between Thunder Bay and Rainy River.

Although many of the roads that make up the route were constructed before the highway was designated, Highway 11 became a provincial highway in 1920 when the network was formed. At the time, it only extended to north of Orillia. In 1937, the route was extended to Hearst, northwest of Timmins. The route was extended to Nipigon by 1943. In 1965, Highway 11 was extended to Rainy River, bringing it to its maximum length. The section through Barrie and south to Toronto was decommissioned as a provincial highway in phases in the late 1990’s. Since then, ongoing construction resulted in the highway being four-laned as far north as North Bay by 2012. A section concurrent with Highway 17 east of Thunder Bay was rebuilt as a divided highway in the early 2010s and work continues. The two-lane Nipigon River Bridge was replaced with a twin-span bridge that opened in 2018.
