Craugastor mexicanus is a species of frog in the family Craugastoridae. It is endemic to eastern Mexico and occurs in the states of Oaxaca, Puebla, Hidalgo, and Veracruz. It is a common species inhabiting tropical wet and semi-deciduous forest, pine-oak montane forest, and montane cloud forest at elevations of 700m–3420mm (2,300feet–11,220feetm) above sea level. Although it is adaptable to habitat disturbance, loss of cloud forest is a potential threat to it. Also chytridiomycosis can have negative impacts. It is present in a number of protected areas, including Cofre de Perote National Park, Tehuacán-Cuicatlán Biosphere Reserve, and Cuenca Hidrográfica Río Necaxa.
