The City of Melbourne is a local government area in Victoria, Australia, located in the central city area of Melbourne. In 2021, the city has an area of 37.7 square kilometres (14.6 sq mi) and had a population of 149,615. The city's motto is "vires acquirit eundo" which means "we gather strength as we go".

Local government is the third-level of government in Australia, administered with limited autonomy under the states and territories, and in turn beneath the federal government. Local government is not mentioned in the Constitution of Australia, and two referendums in 1974 and 1988 to alter the Constitution relating to local government were unsuccessful. Every state/territory government recognises local government in its own respective constitution. Unlike the two-tier local government system in Canada or the United States, there is only one tier of local government in each Australian state/territory, with no distinction between counties and cities.
