The great hornbill, also known as the concave-casqued hornbill, great Indian hornbill or great pied hornbill, is one of the larger members of the hornbill family. It occurs in the Indian subcontinent and Southeast Asia. It is predominantly frugivorous, but also preys on small mammals, reptiles and birds.

The great hornbill is native to the forests of India, Bhutan, Nepal, mainland Southeast Asia and Sumatra. Its distribution is fragmented in the Western Ghats and in the foothills of the Himalayas.
