The Marlboro Cup Invitational Handicap was a Thoroughbred horse race first run in September 1973 at Belmont Park in Elmont, New York. A Grade 1 race for horses 3 years old and up, it was raced over a distance of 1+1⁄8 miles on a dirt track. The advent of the Breeders' Cup races in 1984 marked the beginning of the end for the Marlboro Cup. In 1987, the 15th edition of the race attracted just five horses and was picked up for broadcast on cable television only.
