James Street is a Lower City arterial road in Hamilton, Ontario, Canada. It starts off at the base of the Niagara Escarpment from James Mountain Road, a mountain-access road in the city. It was one of many arterials in the central business district converted to one-way operation in 1956 when the city retained Wilbur Smith and Associates to develop a Traffic and Transportation Plan. Parts of it were restored to two-way operation in 2002. It extends north to the city's waterfront at the North End where it ends at Guise Street West right in front of the Harbour West Marina Complex and the Royal Hamilton Yacht Club.
