Fort Ethan Allen was an earthwork fortification that the Union Army built in 1861 on the property of Gilbert Vanderwerken in Alexandria County (now Arlington County), Virginia, as part of the Civil War defenses of Washington (see Washington, D.C., in the American Civil War). The remains of the fort are now within Arlington County's Fort Ethan Allen Park.
