The red-faced spider monkey (Ateles paniscus), also known as the Guiana spider monkey or red-faced black spider monkey, is a species of spider monkey found in the rain forests in northern South America. The species faces issues with hunting and habitat loss, so is listed as Vulnerable on the IUCN Redlist.

Sexual dimorphism in the species is small; the head-body length of the male is 55.7 cm (21.9 in) on average, while the female is around 55.2 cm (21.7 in) in length.
