Airport Road is an 81 km (50 mile) major north–south urban and rural thoroughfare in Ontario, Canada, running through the Regional Municipality of Peel and Dufferin County.

It then straightens to join the main road grid and runs northwest, passing the operations centre for Air Canada, the airport's cargo facilities, and the east end of Runway 36R, a popular location for planespotting.

[3] At Derry Road, the street enters the Malton neighbourhood, dipping under the tracks hosting GO Transit's Kitchener Line commuter trains just north of the intersection.

Airport Road continues through more industrial areas, passing under the rail spur serving the Brampton Assembly (Stellantis Canada) auto plant.

North of Caledon East it enters the Oak Ridges Moraine and the first of the trademark hills that define much of rural Airport Road.

At Highway 9, it runs through the rural community of Mono Mills as it leaves Peel Region and enters Dufferin County, where the hills become steeper as it traverses the Niagara Escarpment.
