The tufted gray langur (Semnopithecus priam) is an Old World monkey, one of the species of langurs. This, like other gray langurs, is a leaf-eating monkey. It is found in southeast India and Sri Lanka.[1] It is one of several Semnopithecus species named after characters from The Iliad, along with Semnopithecus hector and Semnopithecus ajax. There are two subspecies, Semnopithecus priam thersites in Sri Lanka and the southern Western Ghats in India, and Semnopithecus priam priam from Andhra Pradesh to Tamil Nadu in India.

In Sri Lankan subspecies, dorsal area gray to brownish gray in color, getting darker with the age. Underparts are light grayish. Short whitish beard and sideburns present. The hairs of the crown form a distinct tuft, hence the name. Black eyebrows project outward. Head scarcely paler or not paler than back. Hands and feet are same color as limbs.

In Sinhala language, it is known as හැලි වදුරා.
