The City of Wyndham is a local government area in Victoria, Australia in the outer south-western suburbs of Melbourne, within the Melbourne Metropolitan Area, between Melbourne and the regional city of Geelong. It has an area of 542 square kilometres (209 sq mi). The city had a population of 292,011 as of the 2021 census. For the year to 2018 the City of Wyndham increased its population by 14,251, the largest number of any LGA in Victoria, as well as being the second most populous and the second fastest growing at a rate of 5.9 per cent.

The Wyndham District was first incorporated as a local government entity on 6 October 1862. Under changes made to Local Government legislation, it became the Shire of Wyndham on 7 March 1864 and was renamed the Shire of Werribee on 15 December 1909.

With an initial size of 715 square kilometres (276 sq mi) and being largely rural in character, the shire ceded land to metropolitan Melbourne as suburban development encroached. On 6 January 1922 and 5 February 1941, the City of Footscray annexed two parcels of land totalling about 700 hectares. On 20 February 1957, the Altona Riding of the Shire of Werribee was severed and incorporated as the Shire of Altona, which became a City eleven years later. After this, the boundaries remained fairly stable, and on 20 March 1987 Werribee was proclaimed a City.

On 15 December 1994, during major restructuring of Victoria's local governments, Werribee changed less than most – losing only some rural land around Exford in its north to the Shire of Melton, and Laverton Reserve on its eastern boundary to the City of Hobsons Bay. After 85 years of being known as Werribee, the area's former name of Wyndham was restored.

The City is home to numerous new housing estates in suburbs such as Williams Landing, Point Cook, Wyndham Vale, Truganina, Tarneit and Manor Lakes. The following table presents data from official census and other publications by the Australian Bureau of Statistics:

The City of Wyndham is divided into three wards (Chaffey, Harrison and Iramoo) and is represented by eleven elected councillors. The Victorian Electoral Commission undertook a representation review in 2011–2012, which resulted in the former Truganina ward being renamed Harrison ward. Ward boundaries were also redrawn. The council has adopted a portfolio system for councillors from 2013 onward.
