King's Highway 10, commonly referred to as Highway 10, is a provincially maintained highway in the Canadian province of Ontario. The highway connects the northern end of Highway 410 just north of Brampton with Owen Sound on the southern shores of Georgian Bay, passing through the towns of Orangeville and Shelburne as well as several smaller villages along the way. It historically followed the Toronto–Sydenham Road, the southern part of which later became the southern section of Hurontario Street. The section between Orangeville and Primrose was formerly part of Prince of Wales Road, which continues northwards after the highway turns west.[4] Between Chatsworth and Owen Sound, Highway 10 is concurrent with Highway 6.

Highway 10 was established in 1920 as one of the original provincial highways in Ontario, connecting Highway 5 in Cooksville with Owen Sound. It was extended south by 1937 to Highway 2 in Port Credit. That same year, it became the site of the first highway interchange in Canada at its intersection with The Middle Road. Since the late 1990s, the southern portion has been truncated to its current terminus north of the BramptonCaledon border.
