King's Highway 55, commonly referred to as Highway 55 and historically as the Niagara Stone Road and Black Swamp Road, was a provincially maintained highway in the Canadian province of Ontario, which connected the Queen Elizabeth Way (QEW) with Niagara-on-the-Lake, following Niagara Stone Road. The route divided a swath of wineries at the foot of the Niagara Escarpment, passing at an oblique angle to the concession road grid.

A former Highway 55 designation connected Highway 6 with Highway 53, passing through the Mountain district of Hamilton. The more recent designation was applied in 1970, following the establishment of the Regional Municipality of Niagara. On April 1, 1997, Highway 55 was transferred to Niagara and designated as Niagara Regional Road 55.
