Great Andaman is the main archipelago of the Andaman Islands of India. It comprises five major islands. From north to south, these are North Andaman, Middle Andaman, South Andaman, Baratang and Rutland Island. The three northern islands are the largest of the entire island group, and the islands' capital, Port Blair, also lies in the archipelago.

Great Andaman is often considered the counterpart to Little Andaman, another island in the Andamans.
