Whitefield is a town in Coös County, New Hampshire, United States, in the White Mountains Region.

The last town to be granted under the English provincial government, Whitefield was chartered on July 4, 1774, exactly two years before adoption of the Declaration of Independence.

Others believe the name originated from earlier references to the snowy white fields one would see upon approach through any of the surrounding mountain passages.

With the entrance of the railroad in the 19th century, tourists discovered the town and its cool, clean mountain air.

They sought relief from the heat, humidity and pollution of coal-era summers in Boston, Hartford, New York and Philadelphia.

Though the actual "diamond" track crossing with rails remains intact as of 2022, "guarded" by the last remaining, historic "ball"-type signal in all of New England, the tracks are mostly disused or torn-up on the old B&M line in both directions from Whitefield, and from St. Johnsbury to Fabyan station, on the Maine Central line east of Whitefield.

[1] Whitefield is drained by the Johns River, which runs through the center of town, and its tributary Bog Brook.

Mirror Lake is a small water body close to Route 3 north of the center of town.

As of January 2006 Whitefield is also served by The Tri-Town Bus, a public transportation route connecting with Lancaster and Littleton.
