Forty Fort is a borough in Luzerne County, Pennsylvania, United States. The population was 4,214 at the 2010 census. Its neighbors are the boroughs of Kingston, Wyoming, and Swoyersville. The Wilkes-Barre Wyoming Valley Airport and the Susquehanna River dike are both located in the borough.
Forty Fort was named for a Revolutionary War-era fort that the town's original settlers built; there were forty of these settlers from Connecticut, so the town was later named Forty Fort. Forty Fort was prominent in the Pennamite-Yankee War and in the American Revolution. In the vicinity of this fort occurred, in 1778, the Battle of Wyoming.
Forty Fort is home to perhaps the oldest building known in northeastern Pennsylvania, the Forty Fort Meetinghouse, located in the borough's cemetery. The meeting house was built in 1806-08. In late October 2005, Forty Fort's Wyoming Seminary Lower School launched a successful attempt to save the building from damage and preserve it as a recollection of past historic memories of Forty Fort. Forty Fort also hosts the historic Nathan Denison house. Denison served as colonel of the militia for the area during the Revolution.
Forty Fort has a strong council/weak mayor form of government. Boyd Hoats Jr. is the current mayor. The current mayor's father, Boyd Hoats, Sr. died in 2005 after a battle with cancer. His son was appointed by the borough council to fill the remainder of his father's term, and he was later elected on his own to his current term.
