The community is named after the colonial Fort Loudoun, built in 1756 during the French and Indian War. A replica of the fort, built in 1993, stands at the corner of US 30 and Brooklyn Road North, at the southeastern corner of the CDP.
A post office called Loudon was established in 1814, and the name was changed to Fort Loudon in 1883.
