The City of Casey is a local government area in Victoria, Australia in the outer south-eastern suburbs of Melbourne. Casey is Victoria's most populous municipality, with a 2021 population of 365,239. It has an area of 409 square kilometres (157.9 sq mi).

The city is named after Lord Casey, the 16th Governor-General of Australia, and was formed in 1994 by the merger of most of the City of Berwick with parts of the Shire of Cranbourne (including Cranbourne itself), and the Churchill Park Drive estate within the City of Knox.

Casey spreads from the base of the Dandenong Ranges in the north to the shoreline of Western Port in the south. It features a wide variety of geographical features, due to its outer metropolitan location.

The north, in the foothills of the Dandenongs, is primarily made up of large blocks of land used for grazing, with some small vineyards in operation. An Urban Growth Boundary has been in place since 2005 to protect this area from future residential subdivision.

South of Cranbourne is mainly farmland, used for market gardening and grazing. A small number of flower farms exist around Junction Village, along with a large chicken processing plant in Clyde. This green area has now been opened up for housing development, in the areas of Cranbourne East, Clyde and Clyde North.

The southern boundary of the municipality is the Western Port shoreline including the fishing villages of Tooradin, Blind Bight, Warneet and Cannons Creek. Protected marine reserves exist along this coastline and extend into the Mornington Peninsula at Pearcedale.

The Cardinia border of the city is formed for some of the boundary by the Cardinia Creek, which is drained through channels into Western Port at its southern end. The popular Riding of the Bounds event takes place along this border, in recognition of Berwick's sister city status with Berwick-upon-Tweed in Northumberland, England.

The City of Casey is divided into six wards. The wards are: Balla Balla, Edrington, Four Oaks, Mayfield, River Gum and Springfield.

Elections are held every four years with voters in Balla Balla Ward electing one councillor and all other wards electing two councillors per ward. The eleven councillors vote each year to elect a mayor.

In February 2020, the Victorian Minister for Local Government, Adem Somyurek, dismissed all Casey councillors following a report from municipal monitor Laurinda Gardner that found significant governance failures at the council. Somyurek then appointed Noelene Duff as interim administrator.

In May 2020 Somyurek appointed Noelene Duff PSM, Cameron Boardman and Miguel Belmar as Council administrator panel, to remain until October 2024.

The 2021 census, the city had a population of 365,239 up from 299,301 in the 2016 census
