Incilius pisinnus (common name: Michoacan toad) is a species of "true" toads in the family Bufonidae. It is endemic to Mexico and known from the Tepalcatepec Valley in Michoacán. Prior to its description in 2005, it was mixed with Incilius coccifer and Incilius cycladen. The specific name pisinnus, from the Latin word for "small", refers to the comparatively small size of this species among its close relatives.
