King's Highway 127, commonly referred to as Highway 127, is a provincially maintained highway in the Canadian province of Ontario. The route begins in Maynooth, connecting Highway 62 north of Bancroft with Highway 60 in the township of South Algonquin, east of Whitney and Algonquin Provincial Park. The entire route is patrolled by the Ontario Provincial Police (OPP).

Highway 127 was designated in late 1955, generally following the same route as today, with the exception of the northern terminus. During the early 1960s, a new road was constructed east of Whitney, bypassing the old highway for several kilometres. By 1963, the bypass was complete and Highway 127 was rerouted onto it.
