Riverside South, Ottawa

Riverside South is a suburban community in Gloucester-South Nepean Ward in the south end of the city of Ottawa, Ontario, Canada, just southwest of Ottawa Macdonald–Cartier International Airport. Prior to amalgamation in 2001, the area was located in the city of Gloucester. Its population, according to the Canada 2021 Census, was 19,802.

In the early 1990s this area was mostly vacant with a few houses and some farms. The first homes in the community were built in 1996. Since then, there has been extensive housing development that seems to be growing at the pace of other major suburban communities in the region, such as Barrhaven, Kanata and Orléans.

Currently, most of the built up area of the community is limited to areas around River Road and Earl Armstrong Road, and just west of Limebank Road. It is planned that Riverside South will become a major community with south expansions closer to Manotick and to the east closer to Leitrim. According to the Riverside South Community Association, the boundaries will eventually be "Leitrim Road to the north, the Rideau River to the west, a line half-way between Earl Armstrong and Rideau Road to the south and Bowesville Road to the east. It is expected that the community will have a population of 24,920 by 2034.

The Riverside South community also includes the much older community of Honey Gables, which includes three streets on the west side of River Road. This community was first built c. 1950, and has been under pressure by the surrounding developments.
