The City of Edmonton has experienced a series of municipal boundary adjustments over its history since originally incorporating as a town in 1892 through incorporation as a city, amalgamation or annexation of other urban municipalities, annexation of rural lands from its surrounding neighbours, and separation of lands back to its rural neighbours. Its most recent annexations, which came into effect on January 1, 2019, involved acquisition of lands from predominantly Leduc County as well as Beaumont and Sturgeon County.
