Northern Andamanese is the critically endangered native language of North Andaman Island. It is closely related to Akakede and seems to have consisted of four mutually intelligible dialects: Akachari (Cari), Akakhora (Kora), Akabo (Bo), and Akajeru (Jeru). Jeru is the only one with speakers remaining.
When the North Andamanese people were resettled to Strait Island, a koiné developed from the resulting mixture of dialects. It went extinct in the early 2000s.
