Mattawamkeag is a town in Penobscot County, incorporated on February 14, 1860 from Mattawamkeag Plantation on the site of an ancient Indian village.
The Mattawamkeag River, on which the town is located as it enters the Penobscot, is the largest eastern tributary of the Penobscot. The junction of the two rivers is marked by a gravel bar at the entrance to the Mattawamkeag, whose Indian name is often translated as a river with many rocks at its mouth.
Henry David Thoreau visited the area in 1847 and explored the areas frequented by Indians in earlier times.
Today, a 1,000 acre Wilderness Park is situated between the two rivers with campsites, fishing, swimming and hiking available.
