'''''Trachypithecus''''' (derived from Greek {{lang|grc|τραχύς}}, {{transliteration|grc|trachýs}} meaning "rough" and {{lang|grc|πίθηκος}}, {{transliteration|grc|píthekos}} meaning "monkey") is a genus of [[Old World monkey]]s containing species known as '''lutungs''', '''langurs''', or '''leaf monkeys'''. Their range is much of [[Southeast Asia]] (northeast [[India]], [[Vietnam]], southern [[China]], [[Borneo]], [[Thailand]], [[Java]], and [[Bali]]).

The name "lutung" comes from the [[Sundanese language]] meaning "blackness", ultimately from [[Proto-Austronesian language|Proto-Austronesian]] *''luCuŋ'' (which originally referred to the [[Formosan rock macaque]]);<ref>{{cite web|url=https://acd.clld.org/cognatesets/30116#4/8.58/110.89|title=*luCuŋ: the Formosan rock monkey; Macaca cyclopis|last1=Blust|first1=Robert|author-link=Robert Blust|last2=Trussel|first2=Stephen|website=Austronesian Comparative Dictionary|date=2010|publisher=Max Planck Institute for Evolutionary Anthropology|access-date=8 November 2022}}</ref> it is preferred in one paper because the authors wanted the name langurs to only refer to monkeys in the genus ''[[Semnopithecus]]'',<ref name=Harding2010/> although some "lutungs" are now "langurs" again.<ref name=handbook>{{cite book|title=Handbook of the Mammals of the World, Volume 3: Primates|chapter=Introduction|edition=1st|author=Wilson, Don E. |author2=Mittermeier, Russell A. |author3=Rylands, Anthony B.|chapter-url=https://www.lynxeds.com/hmw/introduction/introduction-hmw-volume-3-primates|access-date=2018-08-30|year=2012|publisher=Lynx Edicions|isbn= 978-84-96553-89-7 }}</ref><ref name=asian>{{cite journal |author=Roos, C. |author2=Boonratana, R. |author3=Supriatna, J. |author4=Fellowes, J.R. |author5=Groves, C.P. |author6=Nash, S.D. |author7=Rylands, A.B. |author8=Mittermeier, R.A. |year=2014 |title=An updated taxonomy and conservation status review of Asian primates |journal=Asian Primates Journal |volume=4 |issue=1 |pages=2–38|url=http://static1.1.sqspcdn.com/static/f/1200343/25106535/1403670682630/2014June24_APJ_Vol4_1.pdf?token=EY6Cm%2BAdyf9lSBug8Jv%2BeF%2B%2BPDM%3D|access-date=2018-08-30}}</ref><ref>{{cite journal|title=Molecular phylogeny and biogeography of langurs and leaf monkeys of South Asia (Primates: Colobinae)|author=Karanth, K.
