Acton is a town in York County, Maine, United States.

It was part of the extensive Ossipee Tract sold on November 28, 1668, by Newichawannock Chief Captain Sunday (or Wesumbe) to Francis Small, a trader from Kittery.

Small sold a half interest in the tract to Major Nicholas Shapleigh of Eliot.

In 1779, Joseph Parsons built a gristmill on the Salmon Falls River near Wakefield, New Hampshire.

In 1877, a vein of silver was discovered near Goding Creek and the Lebanon border.

In 1866, the Shapleigh & Acton Agricultural Society was formed and commenced sponsoring an annual fair and cattle show.
