McCowan Road is a major north-south thoroughfare in the Greater Toronto Area, Canada.
North of Sheppard Avenue, CP Rail's Toronto marshalling yards use McCowan as a western limit, and stretch east of Markham Road.
It is interrupted by a brief 375-meter gap north of Eglinton Avenue due to Highland Creek, where McCowan Park and John McCrae Public School are located.
Formerly known as 7th Line in Markham, McCowan Road now intersects Highway 401 at the Scarborough Town Centre, built in 1973.
The Scarborough Rapid Transit Line, opened in 1985, crosses McCowan on an elevated track at this location.
