King's Highway 4, also known as Highway 4, is a provincially maintained highway in the Canadian province of Ontario. Originally much longer than its present 100.8 km (62.6 mi) length, more than half of Highway 4 was transferred to the responsibility of local governments in 1998. It travels between Highway 3 in Talbotville Royal, north-west of St. Thomas, and Highway 8 in Clinton, passing through the city of London inbetween.

Highway 4 was first designated in 1920, when a 51-kilometre (32 mi) route between Talbotville Royal and Elginfield was assumed by the Department of Highways. It was extended in the early 1930s both south to Port Stanley as well as north to Flesherton.
