Westfield is a town in Aroostook County, incorporated on March 7, 1905 from Westfield Plantation. It is composed of two half-township originally dedicated to helping schools in Massachusetts: the Deerfield Academy Grant and the Westfield Academy Grant.
The first settlers, James Thorncraft and his wife, came in 1839 and lived alone clearing the land until neighbors moved to the area in 1841.
In 1861 the two grant areas were organized for election purposes, and 1863 saw the first schoolhouse built.
Westfield village lies between U.S. Routes 1 and 1A just north of Mars Hill in Aroostook County's potato country.
