The Anzac biscuit is a sweet biscuit, popular in Australia and New Zealand, made using rolled oats, flour, sugar, butter (or margarine), golden syrup, baking soda, boiling water, and (optionally) desiccated coconut. Anzac biscuits have long been associated with the Australian and New Zealand Army Corps (ANZAC) established in World War I.

It has been claimed that these biscuits were sent by wives and women's groups to soldiers abroad because the ingredients do not spoil easily and the biscuits kept well during naval transportation.

Anzac biscuits should not be confused with hardtack, which was nicknamed "ANZAC wafers" in Australia and New Zealand.

Anzac biscuits are an explicit exemption to an Australian ban on commercial goods that use the term "Anzac", so long as they are sold as biscuits and not cookies.
