Fort Charlotte, Military fort and museum in Mobile, United States.

Fort Charlotte is a military fort and museum in Mobile featuring exhibits, reconstructed walls, and barracks that demonstrate colonial military architecture and defense strategies from that era. The site preserves the layout and structures that illustrate how a frontier garrison was organized and equipped.

Mobile was founded in 1702 as Fort Louis de la Louisiane; after floods and a yellow fever outbreak, the settlement moved downriver in 1711 and a wooden Fort Louis was raised on the present site. In 1723 the French began a brick-and-stone fort, renamed Fort Condé for Louis Henri de Bourbon, prince de Condé. Britain took Mobile in 1763 and called it Fort Charlotte; Spain held it from 1780 as Fuerte Carlota, and the United States occupied it in 1813. Congress ordered its sale and removal in 1820.

The fort was named after Queen Charlotte, wife of King George III, reflecting British colonial rule in this region. The name remains a reminder of the English influence that shaped Mobile's history.

The replica stands at 4/5 scale and covers about a third of the original fort's footprint, so the circuit is short. It sits downtown near the Conde–Charlotte House museum, within the area once enclosed by the fort's southern bastions. The 1725 Pauger map shows the original seven-pointed star plan, useful for comparing with what survives.

The site opened as a museum on July 4, 1976, deliberately chosen to coincide with the nation's bicentennial celebration. This timing linked the fort's restoration to a major milestone in American history.
