Freshwater yabbies are crayfish of the genus Cherax (infraorder Astacidea, family Parastacidae). They are often caught for food. A widespread species is the common yabby, Cherax destructor.
Marine yabbies are ghost shrimps (infraorder Thalassinidea), which live in deep burrows in the intertidal zone. They are used as bait for fishing, especially in Queensland and northern New South Wales. A common species in south-eastern Australia is the Bass yabby, Trypaea australiensis.
The name is derived from the word yabij in the Aboriginal language Wemba.

Yabbies are active burrowers and are very hardy, able to withstand poor water quality and long periods of drought.
Restrictions on methods of gathering yabbies, especially the prohibition of "opera house" nets and other enclosed nets for the capture of yabbies and other freshwater crayfish in rivers and streams relate more to the protection of other wildlife, such as platypus and water rats, than to any attempt to restrict the take of yabbies.
Yabbies themselves, in the smaller sizes, make excellent bait for the larger native fish, being an important part of the diet of many species.
