Foster is a dairying and grazing town 174 kilometres (108 mi) south-east of Melbourne on the South Gippsland Highway in Victoria, Australia.

The post office opened on 20 February 1871 as Stockyard Creek and was renamed Foster in 1879 when the township was established.

When the gold ran out, Foster became a service centre of the burgeoning South Gippsland dairy industry.

In summer, the town's temporary population can increase by as much as two and a half fold due to tourism.

The Great Southern Rail Trail links Foster to Leongatha in the west and Yarram in the east.
