The '''Dryas monkey''' ('''''Chlorocebus dryas'''''), also known as '''Salonga monkey''', '''''ekele''''', or '''''inoko''''', is a little-known species of [[Old World monkey]] found only in the [[Congo Basin]], restricted to the left bank of the [[Congo River]]. It is now established that the animals that had been classified as ''Cercopithecus salongo'' (the common name being '''Zaire Diana monkey''') were in fact Dryas monkeys.<ref>{{cite journal|last=Colyn|first=M. |author2=Gautier-Hion, A. |author3=Vanden Audenaerde, D. T.|year=1991|title=''Cercopithecus dryas'' Schwarz 1932 and ''C. salongo'' Vanden Audenaerde, Thys 1977 are the same species with an age-related coat pattern|journal=Folia Primatologica|issue=3|pages=167–170|doi=10.1159/000156543|volume=56|pmid=1885114 }}</ref> Some older sources treat the Dryas monkey as a subspecies of the [[Diana monkey]] and classify it as ''C. diana dryas'', but it is geographically isolated from any known Diana monkey population.

While the Dryas monkey had been considered [[data deficient]], evidence suggests it is very rare and its total population possibly numbers fewer than 200 individuals. Consequently, its status was changed to [[critically endangered]] in the 2008 [[IUCN Red List]].<ref name=iucn>{{Cite iucn | author = Hart, J. | author2 = Butynski, T.M. | author3 = Hurley, M. | name-list-style=amp| title = ''Cercopithecus dryas'' | volume = 2008 | page = e.T4216A10645463 | date = 2008 | doi = 10.2305/IUCN.UK.2008.RLTS.T4216A10645463.en }} Database entry includes justification for why this species was listed as critically endangered</ref> Along with being listed by the IUCN, this species is also listed on Appendix II of [[CITES]].<ref name=iucn/> However, in January 2019 the IUCN status was changed to [[endangered]] following the discovery of this species at eight locations in [[Lomami National Park]].<ref>{{cite web | first=Terese | last=Hart| url=http://www.bonoboincongo.com/2019/04/14/critically-endangered-not-anymore/ | title=Dryas monkey: Critically Endangered?
