The Ten Degree Channel is a strait that separates the Andaman Islands and the Nicobar Islands in the Bay of Bengal. It is named as it lies on the 10-degree line of latitude, north of the equator.
The Ten Degree Channel is a significant geographical feature marking the separation between the two major island groups of the Andaman and Nicobar archipelago.
Other important channels in the region include the Duncan Passage which separates South Andaman and Little Andaman, and the Great Channel which separates Great Nicobar from Sumatra (Indonesia). The Gulf of Mannar and Palk Strait are located between India and Sri Lanka.
