Mucho Macho Man is an American Thoroughbred racehorse who won the 2013 Breeders' Cup Classic. He was foaled in Florida and named after the Village People song "Macho Man". His breeders were Carole and John Rio of Florida, who owned his dam. His foalhood nickname was "Lazarus" because he appeared lifeless at birth, but spontaneously revived. He grew to be a very large horse, standing over 17 hands high. Throughout most of his racing career, Mucho Macho Man was primarily owned by Dean and Patti Reeves of Reeves Thoroughbred Racing of Suwanee, Georgia. They purchased a majority interest in him after his first race in 2010, and in 2012 became his sole owners. In February 2014, Frank Stronach purchased an undisclosed share in the horse on behalf of his Adena Springs Farms, owner of Mucho Macho Man's sire, Macho Uno.

The Breeders' Cup Classic is a Grade I Weight for Age thoroughbred horse race for 3-year-olds and older run at a distance of 1+1⁄4 miles (2,000 m) on dirt. It is held annually at a different racetrack in the United States as part of the Breeders' Cup World Championships in late October or early November. All of the races to date have been held in the United States except for the 1996 edition held at Woodbine Racetrack in Toronto, Canada.
