The golden-bellied capuchin (Sapajus xanthosternos), also known as the yellow-breasted or buffy-headed capuchin, is one of several species of New World monkeys. Although there are differences between individuals as well as between the sexes and across age groups, C. xanthosternos is described as having a distinctive yellow to golden red chest, belly and upper arms. Its face is a light brown and its cap for which the capuchins were first named is a dark brown/black or light brown. Formerly thought to be a subspecies of tufted capuchin (C. apella), it was elevated to the status of species.
