The Tarai gray langur (Semnopithecus hector) is an Old World monkey, and was formerly considered a subspecies of the northern plains gray langur. The species is listed as near threatened, as there are probably not many more than 10,000 mature individuals, and it is experiencing a continuing decline.

## Behaviour and ecology

The Tarai gray langur is arboreal, mainly terrestrial, diurnal, folivorous, and lives in multi-male multi-female groups. Groups have been observed feeding in orchards and crop fields outside of Rajaji National Park.
