Crax rubra has a wide but now highly fragmented distribution from San Luis Potosí, Tamaulipas, Querétaro, Hidalgo, Puebla, Veracruz, Oaxaca, Tabasco, Chiapas and the Yucatán peninsula, Mexico (Howell and Webb 1995a, F. González-García in litt. 1998, M. Martínez-Morales in litt. 1998), south through Belize, Guatemala, El Salvador, Honduras, Nicaragua, Costa Rica and Panama to west Colombia (Pacific lowlands east to the Gulf of Urabá and the upper Sinú valley) and, very rarely, west Ecuador (Sibley and Monroe 1990, R. S. Ridgely in litt. 1998).
