Mount Royal is an area of Calgary, Alberta and is home to the neighbourhoods of Upper Mount Royal (to the south) and Lower Mount Royal (the northern section, on flat terrain), which are separated by an escarpment that runs along Cameron and Royal Avenues in an east-west direction. Upper Mount Royal has an area redevelopment plan in place.

Upper Mount Royal (along with Elbow Park and Roxboro) is one of Calgary's wealthiest neighbourhoods and is home to some of the city's most expensive estates ranging in age from nearly 100 years old to new. Originally an enclave of the city's American born business elite, the neighbourhood was originally known as 'American hill'. As of 2001, American immigrants still made up 29.2% of the residents. This informal name eventually gave way to the more Canadian name of Mount Royal. These neighbourhoods are concentrated in the Elbow River valley. The area of both neighbourhoods is bounded on the north by 17th Avenue SW and on the west by 14th Street SW.

Despite its name, Mount Royal is not home to the city's Mount Royal University.
