Rockbank is a township and rural locality in Melbourne, Victoria, Australia, 29 km west from Melbourne's central business district. Its Local Government Area is the Shire of Melton. At the 2006 Census, Rockbank had a population of 1,337.
Rockbank Post Office opened on 1 January 1862.
The area lies east of the township of Melton and west of the suburb of Deer Park. The land contains many large volcanic rocks making it poor for cultivating crops. The rocks have been used to build walls between paddocks - characteristic of the area west of Melbourne. Mount Cotterell is the highest land point in the vicinity.
The rich, red volcanic soil in the area has helped build the reputation of local wineries. Rockbank is also the host to Victoria's Annual Olive Festival. The earlier agricultural activities date back to the pastoral exploits of William Cross Yuille on the plains.
The town has an Australian rules football team competing in the Riddell District Football League.
