King's Highway 24, commonly referred to as Highway 24, is a highway in the Canadian province of Ontario that currently begins at Highway 3 in Simcoe, and ends at the southern city limits of Cambridge. The south–north route travels through Brantford, as well as the community of Scotland. Outside of those communities, Highway 24 travels through a predominantly agricultural area.

Highway 24 was established in 1927 between Simcoe and Guelph. Between 1936 and 1938, it was extended northeast to Collingwood, as well as south from Simcoe to Port Dover. Much of the section of highway between Caledon Village and Collingwood followed Hurontario Street (partially as a concurrency with Highway 10), with the section of that historic route from Orangeville and Glen Huron being bypassed. Construction of a new route between Simcoe and Brantford took place in the mid-1960s, bypassing the town of Waterford.

In 1997 and 1998, the majority of Highway 24 – both south of Simcoe, as well as north of and through Cambridge – was transferred to the responsibility of the various counties and regions through which it travelled. The former sections of the route are now known as Norfolk County Highway 24, Waterloo Regional Road 24, Peel Regional Road 24, and County Road 124 in Wellington, Dufferin, Grey and Simcoe Counties.
