This article is about the monkey. For the French metaphysician, see [René Guénon](/source/Ren%C3%A9_Gu%C3%A9non).

The **guenons** (/ɡəˈnɒnz/, /ˈɡwɛn.ənz/) are [Old World monkeys](/source/Old_World_monkey) of the [genus](/source/Genus) ***Cercopithecus*** (/ˌsɜrkəˈpɪθəkəs/). Not all members of this genus have the word "guenon" in their common names — blue monkeys, De Brazza's monkeys, and Diana monkeys are all guenons.

Members of the genus are [endemic](/source/Endemism) to [sub-Saharan Africa](/source/Sub-Saharan_Africa), and most are forest monkeys. Many of the species are quite local in their ranges, and some have even more local [subspecies](/source/Subspecies). Many are [threatened](/source/Threatened_species) or [endangered](/source/Endangered_species) because of [habitat loss](/source/Habitat_loss).

Guenons are [sexually dimorphic](/source/Sexual_dimorphism), with males nearly twice the size of females. Most animals live in one-male groups, though males may live alone or spread out in bachelor groups.[2]

## Classification

The [genus name](/source/Genus_name) *Cercopithecus* comes from [Ancient Greek](/source/Ancient_Greek) κέρκος (*kérkos*), meaning "tail", and πίθηκος (*píthēkos*), meaning "ape". It was named by [Carl Linnaeus](/source/Carl_Linnaeus) in 1758.

Because of changes in [scientific classification](/source/Scientific_classification), some monkeys previously included in this genus are no longer. [Vervet monkeys](/source/Vervet_monkey) and [green monkeys](/source/Green_monkey), for example, were formerly considered as a single species in this genus (*Cercopithecus aethiops)* but are currently in the genus *[Chlorocebus](/source/Chlorocebus).*

In the [English language](/source/English_language), the word "guenon" is apparently of [French](/source/French_language) origin.[3] In French, *guenon* was the common name for all species and individuals, both males and females, from the genus *Cercopithecus*. In all other monkey and apes species, the French word *guenon* designates only the females.[4] The three species such as the [L'hoest's monkey](/source/L'hoest's_monkey), [Preuss's monkey](/source/Preuss's_monkey) and the [sun-tailed monkey](/source/Sun-tailed_monkey) were formerly included in the genus and now listed in a different genus *[Allochrocebus](/source/Allochrocebus)*.[1][5][6]

## Species list

### Hybrids

The [red-tailed monkey](/source/Red-tailed_monkey) (*Cercopithecus ascanius*) is known to hybridize with the [blue monkey](/source/Blue_monkey) (*C. mitis*) in several locations in the wild in Africa.[7]
