Secondary Highway 658, commonly referred to as Highway 658, is a provincially maintained highway in the Canadian province of Ontario. The highway extends 29 kilometres (18 mi) between the city of Kenora and the community of Redditt. For a decade, Highway 658 was numbered as Highway 666, leading to numerous sign thefts and a petition by members of a church on the route. This petition eventually led to the route being renumbered in late 1985.
