Enneabatrachus (meaning "[Quarry] nine frog") is an extinct genus of prehistoric frogs known from the late Jurassic Morrison Formation of the United States[1] and also the Late Jurassic-Early Cretaceous Ksar Metlili Formation of Morocco.[2] The type species is E. hechti (named in 1993),[3] whose remains have been recovered from stratigraphic zone 5.[4]

One specimen has been recovered from Quarry 9 of Como Bluff in Wyoming and another specimen was later reported from Dinosaur National Monument.[1] The Como Bluff specimen was an ilium only a few millimeters long.[1] Indeterminate specimens are known from Morocco.[2]

E. hechti's live weight would have only been a few grams.[1]
