Gloucester (/ˈɡlɒstər/ GLOST-ər) is a former municipality and now geographic area of Ottawa, Ontario, Canada. Located east of Ottawa's inner core, it was an independent city until amalgamated with the Regional Municipality of Ottawa–Carleton in 2001 to become the new city of Ottawa. The population of Gloucester is about 150,012 people (2021 Census).

Gloucester, originally known as Township B, was established in 1792. The first settler in the township was Braddish Billings in what is now the Billings Bridge area of Ottawa. In 1800, the township became part of Russell County, and later Carleton County in 1838. In 1850, the area was incorporated as Gloucester Township, named after Prince William Frederick, Duke of Gloucester and Edinburgh.^[1] Over the years, parts of Gloucester Township were annexed by the expanding city of Ottawa. Gloucester was incorporated as a city in 1981 and became part of the amalgamated city of Ottawa in 2001.
