The ornate titi monkey (Plecturocebus ornatus) is a species of titi monkey and is the smallest member of the family Pitheciidae, which also includes uakaris and saki monkeys. As it is a member of this family, it is classified as a type of New World monkey. It is endemic to eastern Colombia, and the only member of the Plecturocebus moloch group to occur north of the Rios Amazonas/Solimes/Napo axis, living at least 350 km away from the closest other member, the white-tailed titi (Plecturocebus discolor), which lives in the south of Colombia. It was once classified as the same species as the white-tailed titi, but is now officially recognized as its own species. The ornate titi is also terrestrial.
The ornate titi is present on the IUCN Red List of endangered species, being recognized as "Vulnerable", and having a general decrease in population trends.
