Highway 131 was a provincially maintained highway in the Canadian province of Ontario, located in Simcoe County and the city of Barrie. The route, which connected Highway 27 with Highway 90, existed from 1984 through 1997, after which it was transferred to the responsibility of Simcoe County. Highway 131 was a straight rural highway, located west of Barrie's suburban fringe, though since then those suburbs have grown out to reach the former highway. Otherwise, the highway is abutted by the occasional farm and surrounded by several forests.
