Eustis, a town in Franklin County, was organized as a plantation on March 30, 1857 from a portion of Jackson Plantation. On February 18, 1871 it was incorporated as a town.
In 1775 the area had been the scene of Benedict Arnold's march to Quebec. On October 19th, his dwindling force reached Eustis and then pressed on via the north branch of the Dead River, now paralleled by Maine Route 27. With the creation of Flagstaff Lake, the river at Eustis is more like a lake than the modest stream Arnold encountered.
Stratton is the main village in the town and is sometimes mistaken for being a separate community.
