Mount Joy is a community located in the north part of Markham, Ontario, Canada near Highway 48 and 16th Avenue and part of the former Township of Markham.

Mount Joy became a police village in 1907, but absorbed into Markham Village in 1915. A non-farm settlement developed on Main Street North and Peter Street from Beech Street to 16th Avenue. Like Quantztown, the former farm land in the area has given way to new homes. Only a handful of homes on Peter Street, former George Rodd General Store / Mount Joy Post Office and the old Mount Joy Public School (built 1907 and closed 1969) are left of the former police village. The area north of 16th Avenue to Bur Oak Avenue emerged in the 1980s and not part of the original police village.
