Secondary Highway 516, commonly referred to as Highway 516, is a provincially maintained secondary highway in the Canadian province of Ontario. The highway is 103.6-kilometre (64.4 mi) in length, connecting Highway 72 and Highway 642 near Sioux Lookout with Highway 599 north of Savant Lake.
Highway 516 was first assumed by the Department of Highway (DHO), predecessor to the modern Ministry of Transportation of Ontario, in 1956. However, the original route was in Muskoka, between the village of Windermere and Highway 11 east of Utterson. This route was mostly transferred to the newly formed District Municipality of Muskoka in 1972, although a portion near Utterson now forms part of Highway 141. The present-day route of Highway 516 was established circa 1983 and has remained unchanged since.
