Northeast Kingdom
The Northeast Kingdom is the northeast corner of the U.S. state of Vermont, comprising Essex, Orleans and Caledonia counties and having a population at the 2010 census of 64,764. In Vermont, the written term “NEK” is often used. The term “Northeast Kingdom” is attributed to George D. Aiken, former Governor of Vermont and a U.S. senator, who first used the term in a 1949 speech. The area is often referred to by Vermonters simply as “The Kingdom.” Because of its three-county extent, it includes several “gateway” towns: at the southeastern corner, St. Johnsbury, just a few miles from the New Hampshire border; to the north, Newport and Derby, close to the Canada–US border; and to the southwest, Hardwick and Danville. Interstate 91, Interstate 93, U.S. Route 5, and U.S. Route 2 are the main roads that connect travelers to the Northeast Kingdom.
