The Santa Marta white-fronted capuchin (Cebus malitiosus) is a species of gracile capuchin monkey from Colombia. It was formerly considered a subspecies of the Cebus albifrons or a synonym of the Colombian white-faced capuchin (C. capucinus), but Mittermeier and Rylands elevated it to a species in 2013, following previous work by Rylands, Hershkovitz, Cooper and Hernandez-Camacho. The IUCN follows this taxonomy.
The Santa Marta white-fronted capuchin range is restricted to forests near the northwest base of Sierra de Santa Marta in northern Colombia. Males have a head and body about long and a tail about long.
