Ischnocnema is a genus of frogs from eastern Brazil and north-eastern Argentina. They comprise the former Eleutherodactylus from this region, but they are closer to Brachycephalus than the "true" Eleutherodactylus. Consequently, they are now placed in their own genus Ischnocnema in the family Brachycephalidae.
