Fenwick Hall, Georgian plantation house on Johns Island near Charleston, United States

Fenwick Hall is a two-story brick house in the Georgian style located on Johns Island, south of Charleston, South Carolina. It sits on a raised basement, has a hip roof, and features a symmetrical facade that reflects colonial plantation architecture of the 18th century.

John Fenwick acquired the Stono River plantation by 1721 and built the central rectangular brick section of the house around 1730. His son Edward inherited it about 1750, bred English thoroughbreds and laid out a 3 mi (4.8 km) race track beneath today's Maybank Highway. As a Tory in the Revolutionary War, Fenwick had the property confiscated; part was returned by legislation in 1785. In 1787 the plantation was sold to his cousin John Gibbes, when the octagonal wing was added.

Edward Fenwick, who inherited the plantation around 1750, imported and bred English thoroughbreds for racing and laid out a 3 mi (4.8 km) track beneath what is now Maybank Highway. During this period the plantation was called John's Island Stud, the name used in Harrison Fairfax's book on the estate. The two-story brick coach house west of the main house has since been converted into a garage.

The property is on Johns Island south of Charleston, reached via River Road and Maybank Highway. It is a private historic property, so visitors should check whether access is available before planning a trip out there.

The 1787 octagonal wing measures about 50 by 18 feet and holds two rooms split by a staircase; its entrance opens from the northwest corner of the parlor. Edward Fenwick laid out a 3-mile racecourse beneath what is now Maybank Highway, and the coach house west of the house has since been converted into a garage.
