The Patzcuaro frog (Lithobates dunni) is a species of frog in the Ranidae family endemic to the Michoacán state, Mexico, where it is locally known as rana de Pátzcuaro. It occurs in Lake Pátzcuaro, Lake Cuitzeo, and the surrounding streams. It is an aquatic frog living in deep water with abundant nutrients. Reproduction takes place in the streams. This species is considered delicious. Once common, over-exploitation has greatly reduced its abundance.
