Marmorerpeton is an extinct genus of prehistoric stem group-salamanders from the Middle Jurassic of the United Kingdom. They are among the oldest known salamanders.
The genus was first described by Susan E. Evans et al. in 1988, when two species were named: M. freemani, and M. kermacki. The material mainly comprised disarticulated vertebrae, partial jaws, and partial skull roofing bones with heavy sculpture. It was recovered via screenwashing from the "Mammal Bed" of Kirtlington Quarry, Oxfordshire. The bed lies near the boundary of the White Limestone Formation and the overlying Forest Marble Formation (the biota from the "Mammal Bed" can be found at Forest Marble Formation#Paleobiota).
