Australian cuisine is the food and cooking practices of Australia and its inhabitants. As a modern nation of large-scale immigration, Australia has absorbed culinary contributions and adaptations from various cultures around the world, including British, European, Asian and Middle Eastern.

Indigenous Australians have occupied Australia for some 65,000 years, during which they developed a unique hunter-gatherer diet, known as bush tucker, drawn from regional Australian plants and animals. Australia became a collection of British colonies from 1788 to 1900, during which time culinary tastes were strongly influenced by British and Irish migrants, with agricultural products such as beef cattle, sheep and wheat becoming staples in the local diet. The Australian gold rushes introduced more varied immigrants and cuisines, mainly Chinese, whilst post-war immigration programs led to a large-scale diversification of local food, mainly due to the influence of migrants from the Mediterranean, East Asia and South Asia.

Australian cuisine in the 21st century reflects the influence of globalisation, with many fast-food restaurants and international trends becoming influential. Organic and biodynamic foods have also become widely available alongside a revival of interest in bush tucker. Australia exports many agricultural products, including cattle, sheep, poultry, milk, vegetables, fruit, nuts, wheat, barley and canola.  Australia also produces wine, beer and soft drinks.

While fast food chains are abundant, Australia's metropolitan areas have restaurants that offer both local and international foods. Restaurants that include contemporary adaptations, interpretations or fusions of exotic influences are frequently termed Modern Australian.
