Narcondam Island is a small volcanic island part of the Indian territory of Andaman and Nicobar Islands. It is 710 m above sea level at the highest point. The island has an area of 7 km² (2.7 sq mi).

Narcondam is classified as an active volcano. The Indian Coast Guard is building a huge coastal surveillance radar facility at the island. This project was delayed for a long time because it was considered harmful to the local horn bill population.

The Narcondam Hornbill is endemic to the island. It is an endangered species. There is a separate Wildlife sanctuary in the island to protect the horn-bill.

Narcondam is known as a diving destination. There are rocky ridges and steep slopes like chimneys useful for diving. The islands offer gently sloping terrain populated with fields of hard corals and colourful reef fish.
