Astacoidea is superfamily of freshwater crayfish that live in the Northern Hemisphere. The other superfamily of crayfish, Parastacoidea, lives in the Southern Hemisphere. Astacoidea consists of three families: Astacidae (from Europe and western North America), Cambaridae (from eastern North America), and Cambaroididae (from eastern Asia). Crayfish are closely related to lobsters, as shown in the simplified cladogram below.{{cite journal |last1=Wolfe |first1=Joanna M. |last2=Breinholt |first2=Jesse W. |last3=Crandall |first3=Keith A. |last4=Lemmon |first4=Alan R. |last5=Lemmon |first5=Emily Moriarty |last6=Timm |first6=Laura E. |last7=Siddall |first7=Mark E. |last8=Bracken-Grissom |first8=Heather D. |title=A phylogenomic framework, evolutionary timeline and genomic resources for comparative studies of decapod crustaceans |journal=Proceedings of the Royal Society B | date=24 April 2019 |volume=286 |issue=1901 |doi=10.1098/rspb.2019.0079 |pmc=6501934 |pmid=31014217 |doi-access=free }}{{Cite journal| title = An updated classification of the freshwater crayfishes (Decapoda: Astacidea) of the world, with a complete species list| date = 2017| last1 = Crandall | first1 = Keith A.| last2 = De Grave | first2 = Sammy| journal = Journal of Crustacean Biology| volume = 37| issue = 5| pages = 615–653| doi = 10.1093/jcbiol/rux070| doi-access = free}}{{cite journal| author1=Heather D.
