The grey-crowned Central American squirrel monkey (Saimiri oerstedii citrinellus) is a subspecies of the Central American squirrel monkey. Its range is restricted to the Pacific coast of central Costa Rica. The northern end of its range is the Rio Tulin and the southern end of its range is the Rio Grande de Terraba. South of the Rio Grande de Terraba, it is replaced by the black-crowned Central American squirrel monkey, S. oerstedii oerstedii. Populations are very fragmented, and the subspecies does not occur in all locations within its general range. It is the subspecies of Central American squirrel monkey seen in Manuel Antonio National Park in Costa Rica.
