The Pennacook, also known by the names Penacook, and Pennacock, were a North American people of the Wabanaki Confederacy who primarily inhabited the Merrimack River valley of present-day New Hampshire and Massachusetts, as well as portions of southern Maine. They are also sometimes called the Merrimack people.
An Algonquian-speaking tribe, they were more closely related to the Abenaki tribes to the west, north and east, such as the Penobscot and Piguaket or Pawtucket, than to other Algonquian tribes to the south, such as the Massachusett or Wampanoag. This relationship was both linguistic and cultural. But, during the time of early Anglo-European settlement, the Pennacook were a large confederacy, politically distinct and at odds with their northern Abenaki neighbors.
