'''Monkey''' is a common name that may refer to most mammals of the [[infraorder]] [[Simiiformes]], also known as simians. Traditionally, all animals in the group now known as simians are counted as monkeys except the [[ape]]s. Thus monkeys, in that sense, constitute an incomplete [[Paraphyly|paraphyletic]] grouping; alternatively, if apes (Hominoidea) are included, ''monkeys'' and ''simians'' are synonyms.

In 1812, [[Étienne Geoffroy Saint-Hilaire|Étienne Geoffroy]] grouped the [[Ape|apes]] and the [[Cercopithecidae]] group of monkeys together and established the name [[Catarrhini]], "Old World monkeys" ("''singes de l'Ancien Monde''" in [[French language|French]]).<ref name=":0">{{Cite journal |last=Geoffroy Saint-Hilaire |first=M.É. |date=1812 |title=Tableau des Quadrumanes, ou des animaux composant le premier Ordre de la Classe des Mammifères |url=https://www.biodiversitylibrary.org/item/23270#page/107/mode/1up |journal=Annales du Muséum d'Histoire Naturelle |location=Paris |volume=19 |pages=85–122}}</ref><ref>{{Cite book |last=Martin |first=W.C.Linnaeus |url=https://archive.org/details/generalintroduct00martrich |title=A General Introduction the Natural History Mammiferous Animals, With a Particular View of the Physical History of Man, III the More Closely Allied Genera of the Order Quadrumana, or Monkeys |publisher=Wright and Co. printers |year=1841 |location=London |pages=340, 361}}</ref><ref name=":32">{{Cite book |last=Buffon |first=Georges Louis Leclerc comte de |url=https://books.google.com/books?id=wOwEAAAAYAAJ&dq=sapajous+sagoins+buffon+regarder&pg=PA61 |title=Oeuvres complètes de Buffon: avec les descriptions anatomiques de Daubenton, son collaborateur |date=1827 |publisher=Verdière et Ladrange |pages=61 |language=fr}}</ref> The extant sister of the Catarrhini in the monkey ("singes") group is the [[Platyrrhini]] (New World monkeys).<ref name=":0" /> Some nine million years before the divergence between the Cercopithecidae and the apes,<ref>{{Citation |title=Family Cercopithecidae Cercopithecids: Old World Monkeys |url=http://dx.doi.org/10.5040/9781472926920.part-0018 |work=Mammals of Africa : Primates |year=2013 |publisher=Bloomsbury Publishing (UK) |doi=10.5040/9781472926920.part-0018 |isbn=978-1-4729-2692-0 |access-date=2022-07-13|url-access=subscription }}</ref> the Platyrrhini emerged within "monkeys" by migration to South America {{citation needed span |date=May 2022 |from Afro-Arabia (the Old World),|reason="O'Neill2012" cite says "drifted to South America either from North America or Africa"}}<ref>{{Cite journal |last=Seiffert |first=Erik R. |date=2012-12-19 |title=Early primate evolution in Afro-Arabia |url=https://onlinelibrary.wiley.com/doi/10.1002/evan.21335 |journal=Evolutionary Anthropology: Issues, News, and Reviews |language=en |volume=21 |issue=6 |pages=239–253 |doi=10.1002/evan.21335|pmid=23280921 |s2cid=38884357 |url-access=subscription }}</ref><ref>{{Cite journal |last1=Bond |first1=Mariano |last2=Tejedor |first2=Marcelo F. |last3=Campbell |first3=Kenneth E. |last4=Chornogubsky |first4=Laura |last5=Novo |first5=Nelson |last6=Goin |first6=Francisco |date=2015-04-23 |title=Eocene primates of South America and the African origins of New World monkeys |url=http://www.nature.com/articles/nature14120 |journal=Nature |language=en |volume=520 |issue=7548 |pages=538–541 |doi=10.1038/nature14120 |pmid=25652825 |bibcode=2015Natur.520..538B |s2cid=4456556 |issn=0028-0836|hdl=11336/79088 |hdl-access=free }}</ref> likely by ocean.<ref name="O'Neill2012" /><ref>{{Cite journal |last=Kay |first=Richard F. |date=2015-03-06 |title=New World monkey origins |url=https://www.science.org/doi/10.1126/science.aaa9217 |journal=Science |language=en |volume=347 |issue=6226 |pages=1068–1069 |doi=10.1126/science.aaa9217 |pmid=25745147 |bibcode=2015Sci...347.1068K |s2cid=206636402 |issn=0036-8075|url-access=subscription }}</ref>{{better source needed |date=May 2022}} Apes are thus deep in the tree of extant and extinct monkeys, and any of the apes is distinctly closer related to the Cercopithecidae than the Platyrrhini are. 

Many monkey species are tree-dwelling ([[Arboreal locomotion|arboreal]]), although there are species that live primarily on the ground, such as [[baboon]]s.

[[Lemur]]s, [[Lorisidae|lorises]], and [[galago]]s are not monkeys, but [[Strepsirrhini|strepsirrhine]] primates (suborder Strepsirrhini). The simians' [[sister group]], the tarsiers, are also haplorhine primates; however, they are also not monkeys.{{citation needed|date=September 2023}}

Apes emerged within monkeys as sister of the Cercopithecidae in the Catarrhini, so cladistically they are monkeys as well. However, there has been resistance to directly designate apes (and thus humans) as monkeys, so "Old World monkey" may be taken to mean either the Cercopithecoidea (not including apes) or the Catarrhini (including apes).<ref>{{Cite web |url=http://www.gibbons.de/main/introduction/chapter_english01.html |title=Die Gibbons (Hylobatidae): Eine Einführung |trans-title=The gibbons (Hylobatidae): an introduction |first=Thomas |last=Geissmann |website=Gibbon Research Lab |access-date=15 March 2019}}</ref><ref name="Osman1953">{{Cite book |title=Primates comparative anatomy and taxonomy I—Strepsirhini |last=Osman Hill |first=W.

==Historical and modern terminology==
[[File:Portrait of a father.jpg|thumb|The [[Barbary macaque]] is also known as the Barbary ape.]]
According to the ''[[Online Etymology Dictionary]]'', the word "monkey" may originate in a [[German language|German]] version of the ''[[Reynard the Fox]]'' fable, published {{Circa|1580}}. In this version of the fable, a character named Moneke is the son of Martin the Ape.<ref name="Harper">{{cite web |url=http://www.etymonline.com/index.php?term=monkey |title=Monkey |last=Harper |first=D. |year=2004 |publisher=Online Etymology Dictionary |access-date=10 April 2013}}</ref> In English, no clear distinction was originally made between "ape" and "monkey"; thus the 1911 ''[[Encyclopædia Britannica Eleventh Edition|Encyclopædia Britannica]]'' entry for "ape" notes that it is either a synonym for "monkey" or is used to mean a tailless humanlike primate.<ref name=EB11Ape>{{Cite EB1911 |wstitle=Ape |volume=2 |page=160}}</ref> Colloquially, the terms "monkey" and "ape" are widely used interchangeably.<ref name="Webster">{{Cite Merriam-Webster |monkey}}</ref><ref name="CNN-20240323">{{cite news |last=Weisberger |first=Mindy |title=Why don't humans have tails?

Later in the first half of the 20th century, the idea developed that there were trends in [[evolution of primates|primate evolution]] and that the living members of the order could be arranged in a series, leading through "monkeys" and "apes" to humans.<ref name=Dixson1981p13>{{Cite book |last=Dixson |first=A.

Scientific classifications are now more often based on [[monophyly|monophyletic]] groups, that is groups consisting of ''all'' the descendants of a common ancestor. The New World monkeys and the Old World monkeys are each monophyletic groups, but their combination was not, since it excluded hominoids (apes and humans). Thus, the term "monkey" no longer referred to a recognized scientific [[taxon]]. The smallest accepted taxon which contains all the monkeys is the infraorder [[Simian|Simiiformes]], or simians. However this also contains the hominoids, so that monkeys are, in terms of currently recognized taxa, non-hominoid simians. Colloquially and pop-culturally, the term is ambiguous and sometimes monkey includes non-human hominoids.<ref name="ew.com">{{cite web |url=http://www.ew.com/ew/gallery/0,,20483133_20488693_20945431,00.html#20945426 |access-date=8 February 2014 |url-status=dead |archive-url=https://web.archive.org/web/20140222064050/http://www.ew.com/ew/gallery/0,,20483133_20488693_20945431,00.html |archive-date=22 February 2014 |title=10 best monkeys at the movies |last=Susman |first=Gary |publisher=[[Entertainment Weekly]]}}</ref> In addition, arguments have been made for a monophyletic usage of the word "monkey" from the perspective that usage should reflect cladistics.<ref name="Naish2019"/><ref>{{Cite web |url=http://paoloviscardi.com/2011/04/21/apes-are-monkeys-deal-with-it/ |title=Apes are monkeys, deal with it |date=21 April 2011}}</ref><ref>{{Cite web |url=http://evolvingthoughts.net/2012/03/are-humans-apes-monkeys-primates-or-hominims/ |title=Are humans apes, monkeys, primates, or hominims? |date=19 March 2012 |access-date=20 December 2015 |archive-url=https://web.archive.org/web/20151222082856/http://evolvingthoughts.net/2012/03/are-humans-apes-monkeys-primates-or-hominims/ |archive-date=22 December 2015 |url-status=dead}}</ref><ref>{{Cite web |url=http://blog.michael-lawrence-wilson.com/2011/08/10/rehabilitating-monkey/ |title=Rehabilitating "monkey"|date=10 August 2011 }}</ref><ref>{{Cite web |url=https://www.geol.umd.edu/~tholtz/G204/lectures/204scatterlings.html|title=The fossil record: the scatterlings of Africa: the origins of humanity |first=Thomas R. |last=Holtz |publisher=University of Maryland |access-date=6 February 2019}}</ref>

<!-- There are innumerable monkeys in pop culture. Let's not start a laundry list here.-->

===Literature===
[[File:Animals of Hindustan monkeys called bandar that can be taught to do tricks, from Illuminated manuscript Baburnama (Memoirs of Babur).jpg|upright|thumb|Illustration of Indian monkeys known as ''bandar'' from the illuminated manuscript ''[[Baburnama]]'' (Memoirs of Babur)]]
[[Sun Wukong]] (the "Monkey King"), a character who figures prominently in [[Chinese mythology]], is the protagonist in the classic Chinese novel ''[[Journey to the West]]''.

Monkeys are prevalent in numerous books, television programs, and movies. The [[television program|television series]] ''[[Monkey (TV series)|Monkey]]'' and the literary characters [[Monsieur Eek]] and [[Curious George]] are all examples.

Informally, "monkey" may refer to apes, particularly chimpanzees, gibbons, and gorillas. Author [[Terry Pratchett]] alludes to this difference in usage in his ''[[Discworld]]'' novels, in which the [[Librarian (Discworld)|Librarian]] of the [[Unseen University]] is an [[orangutan]] who gets very violent if referred to as a monkey. Another example is the use of [[Simians (Chinese poetry)|Simians in Chinese poetry]].

The [[winged monkeys]] are prominent characters in [[L. Frank Baum]]'s ''[[List of Oz books|Wizard of Oz]]'' books and in the [[The Wizard of Oz (1939 film)|1939 film]] based on Baum's 1900 novel ''[[The Wonderful Wizard of Oz]]''.
