King's Highway 124, commonly known as Highway 124, is a provincially maintained highway in the Canadian province of Ontario. The highway connects Highway 400 in Parry Sound with Highway 11 in Sundridge, a distance of 91.2 km (56.7 mi), including a 15.4 km (9.6 mi) concurrency with Highway 520. It is one of several highways in Central Ontario to provide this connection through the Muskoka and Parry Sound region, and the northernmost provincial highway to do so south of Highway 17.
Travelling north then eastwards from Parry Sound, Highway 124 meets very few provincial routes between Highway 400 and Highway 11; only Highway 520 and Highway 510 intersect the route between the two. After passing through McDougall, Waubamik, McKellar, Fairholme and Dunchurch, the highways travels east through Ahmic Harbour, north of Magnetawan, and through to Sundridge.
Highway 124 was assumed by the Department of Highways (DHO), predecessor to the modern Ministry of Transportion (MTO) in 1955, around the same time that Highway 69 (today largely subsumed into Highway 400) was extended to Sudbury. While several realignments of the initial route were carried out between then and the end of the 1960s, the highway generally remained unchanged until 2011, when it was extended through Sundridge and South River due to the four-laning of Highway 11.
