Spix's white-fronted capuchin (Cebus unicolor) is a species of gracile capuchin monkey. It had previously been classified as a subspecies of the Humboldt's white-fronted capuchin (C. albifrons). Following genetic studies by Boubli, et al, Mittermeier and Ryland elevated it to a full species.
Spix's white-fronted capuchin has a wide range within the upper Amazon Basin in Brazil and Peru. It also occurs in northern Bolivia. It has a head and body length between 36.5 and 37.5 cm (14.4 and 14.8 in) and a tail length of between 42 and 46 cm (17 and 18 in).
