Pleistacantha is a genus of crabs in the family Oregoniidae. The genus occurs throughout many coasts in Europe, Africa, Asia, and Oceania.
== Description == Pleistacantha has a pyriform carapace which is longer than it is wide – at most long. The carapace is densely covered by spines and granules, and its walking legs are lined with spines and spinules. Its first pair of gonopods is slender and, like in all oregoniid crabs, features a longitudinal groove. Males have a tapered abdomen, and depending on the species, the sixth abdominal segment and the telson may be either separate or fused together.
