King's Highway 46, commonly referred to as Highway 46, was a provincially maintained highway in the Canadian province of Ontario that connected Highway 7 with Highway 48 in Victoria County. The route existed between 1937 and 1997, after which it was decommissioned and transferred to the county. In 2001, Victoria County amalgamated into the city of Kawartha Lakes, and the road became known as Kawartha Lakes Road 46. It is 25.7 kilometres (16.0 mi) long, passing through the villages of Woodville, Argyle and Bolsover.
