Otisfield is a town in Oxford County, Maine, United States.

Otisfield is included in the Lewiston-Auburn, Maine metropolitan New England city and town area.

It was granted by the Massachusetts General Court on June 15, 1771 to James Otis, Nathaniel Gorham and other descendants of Captain John Gorham and certain members of his company who had fought in the 1690 Battle of Quebec.

It replaced a 1736 grant which was ruled invalid when the line between New Hampshire and Massachusetts was redrawn to satisfy claims by the heirs of John Mason.

Many early settlers were veterans of the Revolutionary War, with the greater number coming from Groton, Massachusetts.

[3] First called Otis Field Plantation, it was incorporated on February 19, 1798 as Otisfield.

Farming became the principal occupation, with corn, potatoes and hay the chief crops.

[5] Today, Otisfield is largely a recreational area, with camps and summer cottages lining the shores of Pleasant Lake, Thompson Lake, Saturday Pond and Moose Pond.

It borders the towns of Norway to the north, Oxford to the northeast, Poland to the east, Casco and Naples to the south, and Harrison to the west.

Otisfield is known throughout the state of Maine for being the home of the Seeds of Peace Camp.
