The Rhesus macaque (Macaca mulatta) is a species of Old World monkey. It lives both in trees and on the ground. It mainly eats fruit, but will also include 100 different plant species in its diet. It spends most of its day feeding and resting, the rest is occupied with traveling, grooming, and playing.

Rhesus macaques are either pale brown or gray, usually with pink faces. Their tails are quite long, they have a rib cage that is wider than average, with dorsal scapulae, and they have thirty-two teeth. They are charismatic monkeys and like to have fun and can be cheeky. Their coats have faded undertones on the underside. Their faces are furless and in adults - bright red, and adults also have bright red rumps. They have large cheek pouches for storing food while out foraging.

Rhesus macaques are native to India, Bangladesh, Pakistan, Nepal, Myanmar, Thailand, Afghanistan, Vietnam, southern China, and some neighboring areas. They have the widest geographic ranges of any non-human primate, occupying a great diversity of altitudes throughout Central, South, and Southeast Asia. Rhesus macaques may be found in forests, mangroves, scrub, grasslands, and mountainous regions. They also adapt well to human presence and form larger troops in human-dominated landscapes than in forests.

Rhesus macaques are social, diurnal, and both terrestrial and arboreal animals. They walk using four limbs, walking on the ground on both their toes and on the soles of their feet. They are very active and loud. They like being in the water and can swim well. They form groups of as many as 200 individuals, and when the size of a group reaches 80 to 100, a subgroup of females can split off to create a new group. Generally, groups are made up of several unrelated males, with many closely related females. Males and females within a group demonstrate a preference for high-ranking individuals of the opposite sex. Rhesus monkeys are not territorial. Every group of individuals generally has its own sleeping area. Confrontations between different groups are rare. When groups meet, usually the weaker group avoids the stronger one.
