King's Highway 44, commonly referred to as Highway 44, was a provincially maintained highway in the Canadian province of Ontario. The 15.9-kilometre (9.9 mi)-long route began at Highway 15 in the town of Almonte and travelled eastward through Lanark County towards Ottawa, ending at Highway 17 (now Highway 417). Highway 44 was assumed by the province in 1938 along existing unimproved roadway. A significant portion of the highway was incorporated into a new routing of Highway 17 in 1966. The highway alignment remained generally unchanged for the next three decades until it was decommissioned in 1997 and transferred to Lanark County and what is now the City of Ottawa. The road has since been redesignated as Lanark County Road 49 and Ottawa Road 49.
