Just to the south-southwest of Ottawa Macdonald–Cartier International Airport lies the suburban hamlet of Riverside South, which is located in the Gloucester-South Nepean Ward of the city of Ottawa, Ontario, Canada. Riverside South is located near the south end of the city. Before the municipalities were combined in 2001, this region was a part of the city of Gloucester. According to the Census completed in Canada in the year 2021, the population was 19,802.

At the beginning of the 1990s, this region was primarily uninhabited, with just a few residences and a few farms. 1996 was the year that saw the construction of the first residences in the neighbourhood. Since that time, there has been a significant amount of residential construction, and the community appears to be expanding at a rate that is comparable to that of other large suburban towns in the area, such as Barrhaven, Kanata, and Orléans.

At the moment, the majority of the developed land within the neighbourhood is confined to the regions around River Road and Earl Armstrong Road, as well as the area immediately to the west of Limebank Road. It is anticipated that Riverside South will develop into a significant neighbourhood, with extensions to the south closer to Manotick and expansions to the east closer to Leitrim. In the end, the borders will be as follows, as stated by the Riverside South Community Association: “Leitrim Road to the north, the Rideau River to the west, a line halfway between Earl Armstrong and Rideau Road to the south, and Bowesville Road to the east.” By the year 2034, it is anticipated that the population of the neighbourhood would have increased to 24,920 people.
