King's Highway 410, also known as Highway 410 and colloquially as the four-ten, is a 400-series highway in the Canadian province of Ontario that connects Highways 401 and 403 to Brampton. North of Brampton, the commuter freeway ends and the route becomes Highway 10, which continues north through Caledon as a four-lane undivided highway. The route is patrolled by the Ontario Provincial Police and has a speed limit of 100 km/h (62 mph).

The 400-series highways are a network of controlled-access highways in the Canadian province of Ontario, forming a special subset of the provincial highway system. They are analogous to the Interstate Highway System in the United States or the Autoroute system of neighbouring Quebec, and are regulated by the Ministry of Transportation of Ontario (MTO). The 400-series designations were introduced in 1952, although Ontario had been constructing divided highways for two decades prior. Initially, only Highways 400, 401 and 402 were numbered; other designations followed in the subsequent decades. The network is situated almost entirely in Southern Ontario, although Highway 400 extends into the more remote northern portion of the province.
