'''Night monkeys''', also known as '''owl monkeys''' or '''douroucoulis'''<ref>{{cite EB1911 |wstitle=Douroucouli |volume=8 |page=450}}</ref> ({{IPAc-en|d|uː|r|uː|'|k|uː|l|i|z}}), are nocturnal [[New World monkey]]s of the [[genus]] '''''Aotus''''', the only member of the [[family (biology)|family]] '''Aotidae''' ({{IPAc-en|eɪ|'|ɒ|t|ᵻ|d|iː}}). The genus comprises eleven species which are found across Panama and much of South America in primary and secondary forests, tropical rainforests and cloud forests up to {{convert|2400|m|ft}}. Night monkeys have large eyes which improve their vision at night, while their ears are mostly hidden, giving them their name ''Aotus'', meaning "earless".

Night monkeys are the only truly nocturnal monkeys, although some [[Cathemerality|cathemeral]] populations of [[Azara's night monkey]] have irregular bursts of activity during day and night. They have a varied repertoire of vocalisations and live in small family groups of a [[pair bonding|mated pair]] and their immature offspring. Night monkeys have [[monochromacy|monochromatic vision]] which improves their ability to detect visual cues at night.

Night monkeys are threatened by habitat loss, the pet trade, hunting for bushmeat, and by [[biomedical research]]. They constitute one of the few monkey species affected by the often deadly human [[malaria]] [[protozoan]] ''[[Plasmodium falciparum]]'' and are therefore used as experimental subjects in malaria research. The [[Peruvian night monkey]] is classified by the [[International Union for Conservation of Nature]] (IUCN) as an [[Endangered species]], while four are [[Vulnerable species]], four are [[Least-concern species]], and two are data deficient.
