Fort Watauga, more properly Fort Caswell, was an American Revolutionary War fort that once stood at the Sycamore Shoals of the Watauga River in what is now Elizabethton, Tennessee. The fort was originally built in 1775–1776 by the area's frontier government, the Watauga Association, to help defend Watauga settlers from Native American (primarily Cherokee) attacks, which were in part instigated by the British. Fort Watauga was originally named Fort Caswell after North Carolina Governor Richard Caswell.
