Fosters is an Australian brand of beer. By far their most well-known product is Fosters Lager, a typical, mild-tasting commercial lager.

Whilst popular in many countries, where it is often brewed under license, and popularised by advertising making use of stereotypes of Australians as unsophisticated bush-dwellers, Fosters Lager is highly unpopular in its home country, where Victoria Bitter, also made by a company owned by Fosters, is almost universally regarded as a superior low-cost "basic" beer.

The Fosters brand is also used in Australia on several other beers, notably Fosters Light Ice, a low-alcohol lager.

Fosters Brewing Group owns a large number of other beer and wine brands. Other notable products of the company include:

  • Carlton Draught
  • Cascade Lager
  • Cascade Premium
  • Cascade Premium Light
  • Carlton Cold
  • Crown Lager
