The Sentinelese, also known as the Sentineli and the North Sentinel Islanders, are an indigenous people who inhabit North Sentinel Island in the Bay of Bengal in the northeastern Indian Ocean. Designated a particularly vulnerable tribal group and a Scheduled Tribe, they belong to the broader class of Andamanese peoples.

There is no generally accepted definition of Indigenous peoples, although in the 21st century the focus has been on self-identification, cultural difference from other groups in a state, a special relationship with their traditional territory, and an experience of subjugation and discrimination under a dominant cultural model.
