Dixfield is a town in Oxford County, Maine, United States. The population was 2,550 at the 2010 census. The town motto of Dixfield is "The Only One", because it is the only town in the world to claim that name. Dr. Elijah Dix, a substantial landowner in the area, bought the town (and Dixmont) which bears his name.
The Massachusetts General Court granted the township in 1789 to Colonel Jonathan Holman of Sutton, Massachusetts (now Millbury), an American Revolutionary War veteran, together with 25 others. In 1795, the first permanent settlers arrived with their families—John Marble, Gardner Brown, Amos Trask, Levi Newton, David Torrey and John Gould. It was called Holmantown Plantation until part of it was incorporated on June 21, 1803 as Dixfield, the 147th town in Maine (the remainder of the plantation would be incorporated in 1818 as Mexico). Dr. Elijah Dix of Boston, a substantial landowner in the area, promised to donate a library for the town if the citizens changed its name from Holmantown to Dixfield. The citizens complied, after which the town received dusty old boxes of medical books printed in German.
