Black Buck, a small antelope of India. A male black buck stands about 32 inches (80 cm) high at the shoulders and weighs about 85 pounds (39 kg). The coat is deep brown or black above, with white underparts. The horns are from 16 to 20 inches (40 to 50 cm) or more in length. They rise from the top of the head in spiral twists of three to five turns. The doe is usually hornless.

Black bucks were once numerous but their numbers have dwindled. They are found in open ground, grassy plains, or cultivated areas. They travel in herds, sometimes numbering in the hundreds.

The name black buck is also applied to the African sable antelope.

The black buck is Antilope cervicapra of the family Bovidae.
