Welcome to Lyme, NH

Lyme is a rural community located in the Upper Valley region of New Hampshire along the Connecticut River. Some think our name came from Lyme, Connecticut and others mention Lyme Regis, England. The spelling on the original 1761 charter of "Lime" has been attributed to an error by Governor Wentworth's secretary. The original settlers were from Palmer, Belchertown and Brookfield in Massachusetts. Lyme contains 53.8 square miles of land, 28.7 miles of paved and 38.7 miles of gravel roads. In 2010 it had a population of 1,716
