In Colombia, white-fronted capuchins are found from the northern slopes of the Sierra de Santa Marta to the south, in the valley of the Magdalena River to an as yet undefined point in the Department of Tolima and in the valley of the lower Cauca River, to the eastern parts of central Antioquia and the southern parts of Sucre to the west. In Guajira the species is found to Riohacha, and an isolated population is apparently found in the Serranía de Macuira, though this needs confirmation. They are also found along the slopes of the Serranía de Perijá and the Cordillera Oriental. To the east of the Cordillera they are found in Norte de Santander, western Arauca, in eastern Vichada between the Meta and Tuparro rivers, and then south of the Vichada River; although east of the Ariari River, not including the Ariari itself. It is not known whether they are found in the rather extensive forests of the upper Manacasías River in Meta. South of the Guayabero and Guaviare River, white-fronted capuchins are found throughout the Amazon. The species is known to an altitude of in the Department of Tolima.
