It is 178 miles long and joins the Kennebec River at Merrymeeting Bay in Maine before its water empties into the Gulf of Maine on the Atlantic Ocean. Its drainage basin is 3,530 square miles in area. The name "Androscoggin" comes from the Eastern Abenaki term, meaning "river of cliff rock shelters"; or perhaps from Penobscot, meaning "river of rock shelters". The Anglicization of the Abenaki term is likely an analogical contamination with the colonial governor Edmund Andros.
