Pachycentrata is an extinct genus of frogs.

Pachycentrata fossils have been found in the In Beceten Formation located in Tahoua, Niger. A. M. Báez and J.-C. Rage. 1998. Pipid frogs from the Upper Cretaceous of In Beceten, Niger. Palaeontology 41(4):669-691 The fossils have been dated to the late/upper Coniacian to Santonian periods.{{cite web|url=https://paleobiodb.org/classic/checkTaxonInfo?taxon_no=135380 |title=Fossilworks |publisher=Paleodb.org |date= |access-date=17 December 2021}} It is estimated to have snout-vent length about {{convert|7|cm|in}}.

The original phylogenetic analysis suggested that it was more closely related to Pipa than to Xenopus, and a recent phylogenetic supports this conclusion in an unconstrained phylogenetic analysis, but constraining for the topology obtained by molecular studies{{cite journal |last1=Pyron |first1=R.
