Norridgewock was the name of both an Indigenous village and a band of the Abenaki Native Americans/First Nations, an Eastern Algonquian tribe of the United States and Canada. The French of New France called the village Kennebec. The tribe occupied an area in the interior of Maine. During colonial times, this area was territory disputed between British and French colonists, and was set along the claimed western border of Acadia, the western bank of the Kennebec River.
