The Ten Degree Channel is a channel that separates the Andaman Islands from the Nicobar Islands in the Bay of Bengal. The two sets of islands together form the Indian Union Territory of Andaman and Nicobar Islands. The Channel is approximately 150 km wide, running essentially along an east-west orientation. It is so named as it lies on the 10-degree line of latitude, north of the equator.
