Narragansett refers to three very different things:
An Algonquian-speaking Native American tribe that historically inhabited present-day Rhode Island and southeastern Massachusetts. They were a powerful confederacy before European contact. The Narragansett Indian Tribe is federally recognized today, with a reservation in Charlestown, RI.
The extinct Algonquian language once spoken by the tribe. Revitalization efforts are underway using historical records, missionary translations, and comparative linguistics.
Narragansett, RI (town); Narragansett Bay; Narragansett Pier; USCGC Narragansett (Coast Guard cutter). All derive from the tribe's name, meaning "(people) of the small point" or "people of the narrow point."
