Before the Key West extension of the Overseas Railroad was completed, Knights Key was the end of the line and a major seaport existed there. A U.S. Post Office was established there in 1908, and operated until June, 1912. A United States Coast and Geodetic Survey field report written in 1935-1936 states: "The key was named after the original settler and is called locally Knights Key."
The campground and "village" at Knights Key were developed by the Kyle family in the 1960s.
