Cambaridae is the largest of the three families of freshwater crayfish. Most of the species in the family are native to North America east of the Great Divide, such as the invasive Procambarus clarkii, with fewer species living in East Asia and Japan, such as zarigani (Cambaroides japonicus).

A recent molecular study^[1] suggested that the family Cambaridae may be paraphyletic, with the family Astacidae nested within it. The status of the genus Cambaroides remains unclear.
