King's Highway 31, commonly referred to as Highway 31 and historically known as the Metcalfe Road, was a provincially maintained highway in the Canadian province of Ontario. The 76.93-kilometre (47.80 mi) route connected Highway 2 in Morrisburg with the Chaudière Bridge at the Ontario–Quebec boundary in downtown Ottawa.

Established in 1927, Highway 31 originally extended from Highway 2 north to the Stormont, Dundas and GlengarryCarleton county line. It was extended into Ottawa in 1936, and had several routings through the city over the years. The southern terminus was altered with the construction of the St. Lawrence Seaway in 1958, and a bypass of Winchester was opened in 1974. The entire highway was decommissioned in 1997 and 1998, and transferred to lower levels of government. It has since been known as Stormont, Dundas and Glengarry (SDG) County Road 31 outside of Ottawa, and Ottawa Road 31 and several local names within Ottawa, notably Bank Street and Bronson Avenue.
