Cancroidea is a superfamily of crabs, comprising the families Atelecyclidae and Cancridae. Two families previously included in this superfamily have since been separated off into new superfamilies – Cheiragonidae into Cheiragonoidea, Corystidae into Corystoidea – while two others (Pirimelidae, Thiidae) have been transferred to Portunoidea.
