The Southern Professional Floodlit Cup was an association football competition played in the late 1950s, which involved clubs from London, South East England and a small number of teams from the Midlands. The competition started in the 1955–56 season with ten clubs competing and in its final season, 1959–60, the number of entrants had increased to 18. The inaugural competition was won by West Ham United with the other winners being Luton Town, Portsmouth, Arsenal and Coventry City. In 1960, the competition gave way to the Football League Cup which was open to clubs throughout the Football League.^[1]

The competition operated on a straight knockout basis with all ties being decided over single matches, with replays if necessary. The final was played on the home ground of one of the competitors. From 1955–56 to 1958–59, there were four rounds including the final with an extra round in 1959–60 to accommodate the additional entrants.^[2]
