Abnaki (or Abenaki ) Indians, a group of related Algonquian-speaking tribes. Originally, they were divided into two branches. The eastern Abnaki, which included the Kennebec and Penobscot tribes, lived on the Maine coast and were principally a fishing people. The western Abnaki, which included the Winnipesaukee and Pennacook, lived in New Hampshire, Vermont, Massachusetts, and Quebec, and were mainly hunters and farmers. In the 1700's, the Abnaki joined with the Malecite, Passamaquoddy, and Micmac to form the Abnaki Confederacy, which became allied with the French. Most Abnaki were driven into Canada by the British in the 18th century.

There are about 1,000 Abnaki on the Penobscot reservation in Maine, and about 1,000 descendants of western and eastern Abnaki in Quebec. The latter are sometimes called the St. Francis Indians.
