The Indochinese black langur (Trachypithecus selbstus) is a little-known Lutung endemic to Laos and neighboring Vietnam. Because they live in dense forests and rarely venture outside, observing them in the wild can be difficult.

The stump-tailed macaque, also known as the bear macaque, is an Old World monkey endemic to Cambodia, northeastern India, southwestern China, Myanmar, and Laos, from northwestern Peninsular Malaysia, Vietnam, and Thailand.

The lar gibbon (Hylobates lar), also called the white-handed gibbon, is another endangered mammal in the gibbon family, Hylobatidae. It is among the best-known gibbons and is occasionally kept in captivity. Lar gibbons have a two-tone coat.

The southern white-cheeked gibbon (Nomascus siki) is a species of gibbon endemic to Laos and Vietnam. It is closely related to the yellow-cheeked gibbon (Nomascus gabriellae) and northern white-cheeked gibbon (Nomascus leucogenys).

The pileated gibbon (Hylobates pileatus) is a primate in the gibbon family, Hylobatidae. Pileated gibbons are monogamous and typically found in only around 3 percent of mammals.

The northern buffed-cheeked gibbon (Nomascus annamensis) is a species of crested gibbon recently discovered in Vietnam, Laos, and Cambodia. Northern buffed-cheeked gibbons live almost exclusively in trees and rarely leave the canopy's comfort and safety.

The northern white-cheeked gibbon (Nomascus leucogenys), also called the white-cheeked gibbon, is an endangered species of gibbon endemic to Southeast Asia. Like other members of its genus, both males and females have unusually long arms, even for gibbons, with arms 1.2 to 1.4 times the length of their legs.

The southern yellow-cheeked gibbon, also known as a golden-cheeked gibbon, buffed-cheeked gibbon, red-cheeked gibbon, southern yellow-cheeked crested gibbon, or golden-cheeked crested gibbon, is a species of gibbon endemic to Cambodia, Laos, and Vietnam.

Black-crested Gibbons are mainly found in southern China (Yunnan) and some distribution areas in northwestern Laos and northern Vietnam. Black-crested gibbons exhibit sexual dichromatism, with the male being entirely black, while the female is yellowish or tan in color with variable black markings.

The northern pig-tailed macaque (Macaca leonina) is a macaque species in the Cercopithecidae family. Typical of this group of Old World monkeys, northern pig-tailed monkeys are gregarious, living in social groups of 9-81 individuals.

The Annamese langur is another Old-World monkey in the subfamily Colobinae. Annamese langurs are covered in thick, gray fur. They have dark faces, and the space around the eyes is pale and forms a ring, often in the flesh. Trachypithecus margarita is a monotypic species as it has no subspecies.
