Arosaguntacook or Arossagunticook, the tribe's endonym, in the eastern Abenaki language means "Rocky Flats flow" or "a river of rocks refuge." Other recorded variations of the name are Amariscoggin, Ameriscoggin, Asschincantecook, Arossagunticook, Alessikantek-eyak by the Penobscot and the Cowasuck. The name Arosaguntacook was probably changed by Massachusetts Governor Edmund Andros to Androscoggin. Today's Penobscot name for the Saint Francis Abenaki is Alessikantek-eyak because Arossaguntacook belonged to the ancestors of the people of Saint Francis.
The Arosaguntacook once lived in the Androscoggin River watershed, located in present-day southern Maine and northern New Hampshire. Their main village was located in the vicinity of present-day Lewiston. Together with the Pigwacket, they formed the southernmost of the Abenaki tribes, and were therefore one of the first in contact with the English colonists of New England.
