The City of Altona was a local government area about 13 kilometres (8 mi) west of Melbourne, the state capital of Victoria, Australia.

The city covered an area of 40.18 square kilometres (15.51 sq mi), and existed from 1957 until 1994.

The city was named after the town of Altona near Hamburg, Germany, in 1844 by Robert Wrede, a pastoralist and early settler.

Land in the area was first incorporated as part of the Wyndham Road District on 6 October 1862, which became the Shire of Wyndham on 7 March 1864, and was renamed the Shire of Werribee on 15 December 1909.

The facility is still used for council meetings by the City of Hobsons Bay.
