Leroidesanimaux (September 27, 2000 – May 27, 2016) was a Thoroughbred racehorse who competed in Brazil and was an Eclipse Award winner in the United States.

Racing in California for trainer Bobby Frankel, as a four-year-old Leroidesanimaux finished fourth in his American debut.

He then won five consecutive races during which he set a track record for the 1 1/16-mile distance on turf in the Grade III Inglewood Handicap at Hollywood Park Racetrack.

Considered by many racing experts and fans as one of the best turf milers in years, Leroidesanimaux was sent off as the heavy betting favorite in the 2005 Breeders' Cup Mile.

Sold to Richard and Audrey Haisfield, Leroidesanimaux was retired to stud duty at their Stonewall Farm in Versailles, Kentucky.
