Britopygus is an extinct genus of whip spider that lived in Brazil (Crato Formation) during the Early Cretaceous epoch.

The genus is known from a single species, Britopygus weygoldti.

Although it bears similarity to members of the extant family Charinidae, its placement in this clade is not beyond dispute[1] and more recent sources place the genus in Phrynidae.
