| synonyms ref = Its range in India extends from Assam and Meghalaya to eastern Arunachal Pradesh, Nagaland, Manipur, Mizoram and Tripura. It is primarily frugivorous, but eats many types of vegetation, such as seeds, leaves and roots, but also hunts freshwater crabs, frogs, bird eggs and insects.

The stump tailed macaque has long, thick, dark brown fur covering its body, but its face and its short tail, which measures between , are hairless. It is distributed from northeastern India and southern China into the northwest tip of West Malaysia on the Malay Peninsula. A study population was introduced to Tanaxpillo, an uninhabited island in Lake Catemaco, Veracruz, Mexico in 1974, where it ranges in seminatural conditions. This species has no lasting pair bonds and is truly promiscuous, a staple for macaques. Physical violence very rarely occurs, and although minor scraps often flair up and physical intimidation displays occur, they tend to quickly be resolved, resulting in this species being labelled as peaceful. Stump tailed macaques are remarkably unfussy in their eating habits though fruit generally is a staple part of their diet. Stump tail macaques have a large, bulky, muscular build with thick, solid limbs, making them very mobile on land yet quite ungainly in trees, and this unusual physique for a macaque may be responsible for this species unique tendency to consume larger quantities of meat than other macaque species. Stump tail macaques feed on very large quantities of insects, small animals and eggs.

A study population of female stump tailed macaques was found to have increased levels of steroid sex hormones, specifically 17β estradiol and progesterone levels. 17β estradiol levels were significantly greater during summer and fall and progesterone levels were significantly greater during summer, fall and winter. This explains how stump tailed macaques have two mating seasons per year: one in summer (July–August) and one in fall (November). This is supported by the distribution of birth frequency in stump tailed macaques.
