Astacidae is a family of freshwater crayfish native to Europe, western Asia and western North America. The family is made up of four extant (living) genera: The genera Astacus (which includes the European crayfish), Pontastacus (which includes the Turkish crayfish), and Austropotamobius are all found throughout Europe and parts of western Asia, while Pacifastacus (which includes the signal crayfish) is native to western United States and British Columbia, but has also been introduced elsewhere.

Classification and phylogeny

Astacidae belongs to the superfamily Astacoidea, which contains all crayfish in the Northern Hemisphere. Astacoidea is the sister taxon to Parastacoidea, which contains all crayfish of the Southern Hemisphere. Crayfish and lobsters together comprise the infraorder Astacidea, as shown in the simplified cladogram below: |label1=Astacidea |1={{clade |label1=clawed lobsters |1={{clade |label1=Enoplometopoidea |1=Enoplometopidae |label2=Nephropoidea |2=Nephropidae }} |label2=crayfish |2={{clade |label1=Parastacoidea |1=Parastacidae |label2=Astacoidea |2={{clade |1=Cambaroididae |2={{clade |1=Astacidae |2=Cambaridae }} }} }} }} }}
