The Onge are one of the Andamanese indigenous peoples of the Andaman Islands. Traditionally hunter-gatherers, they are a designated as a Scheduled Tribe of India.
In the 18th century the Onge, or Madhumitha, were distributed across Little Andaman Island and the nearby islands, with some territory and camps established on Rutland Island and the southern tip of South Andaman Island. After they encountered British colonial officers, friendly relations were established with the British Empire in the 1800s through Lieutenant Archibald Blair. British naval officer M. V. Portman described them as the "mildest, most timid, and inoffensive" group of Andamanese people he had encountered. By the end of the 19th century they sometimes visited the South and North Brother Islands to catch sea turtles; at the time, those islands seemed to be the boundary between their territory and the range of the Great Andamanese people further north. Today, the surviving members are confined to two reserve camps on Little Andaman, Dugong Creek in the northeast and South Bay.
