Brookfield began as part of Middleton, NH, which was granted by the Masonian proprietors on April 27, 1749, to Ebenezer Varney and others. The Charter was renewed on March 21, 1770, and Middleton was incorporated on March 4th, 1778. The inhabitants of the north or second division of Middleton attempted to incorporate as a separate township in 1785 without success.

Incorporated in 1794, the Town of Brookfield, New Hampshire is located in Carroll County. Brookfield had a population of 712 at the 2010 Census.
