Lyford Cay is a private gated community located on the western tip of New Providence Island in The Bahamas. The Cay is named after Captain William Lyford Jr., a mariner of note in Colonial and Revolutionary times, and is built on a 448-acre grant he received for his services as a Loyalist in the American Revolution. Captain Lyford also received a 92-acre grant on Cat Island, Bahamas for playing a key role in Andrew Deveaux’s raid of mid-April 1783 that drove the Spanish from Nassau.
Considered one of the world's wealthiest and most exclusive neighborhoods, the Lyford Cay Club was built during the latter part of the 1950s by prominent Canadian businessman Edward Plunkett Taylor, who bought the land in 1954 from Bahamian developer Sir Harold Christie. In December 1962, U.S. President John F. Kennedy stayed at E. P. Taylor's home in Lyford Cay while he held talks with British Prime Minister Harold Macmillan.  
Club members, most of whom hail from Britain, Canada, Cuba, France, Greece, Ireland, Switzerland, and the United States, can use a par-72 golf course, twelve tennis courts, a full-service marina, dining facilities, a post office, a private international school, and a mile-long private beach.
