Leonatus (foaled in 1880 in Kentucky, died 1898) was an American Thoroughbred racehorse.

Leonatus was the son of Uncle John Harper's great racer and sire Longfellow, himself a son of the imported English stud Leamington. Leonatus' dam was the Daniel Swigert-bred Semper Felix, whose dam was by the greatest of all nineteenth-century American foundation stallions, Lexington, himself by Boston.

Purchased by the partnership of George Morgan and Jack Chinn, and thereafter stabled in Mercer County, Kentucky, Leonatus was trained by African American horseman Raleigh "Rolla" Colston as well as by John McGinty.

Leonatus raced in a new world of English "dash" races on the kind of racetracks we recognize today.

Racing only once as juvenile, Leonatus finished second. As a three-year-old, he won ten stakes, all in either Kentucky or Illinois, within the space of 49 days. Although there were no official awards given until 1936, this saw him retrospectively regarded as the American Champion Three-Year-Old Male Horse of 1883.

Winning the 1883 Kentucky Derby (run that year on May 23) was a major accomplishment. Carrying 105 pounds and the 2-1 favorite, Leonatus was piloted by William "Billy" Donohue, the jockey who'd ridden Sligo in the 1881 Derby, coming in fourth. Running in mud on a clear, cold day, Leonatus was up against the colt Drake Carter, trained by Green B. Morris, who hoped to take his second consecutive Derby (he'd won with Apollo in 1882). Drake Carter leaped into the lead, but Leonatus caught him at a quarter of a mile. A quarter of a mile farther on, Leonatus was ahead by three lengths. In the homestretch, Lord Raglan made a strong bid, but though it carried him forward, he tired. Leonatus won over Drake Carter by three lengths, earning $3,760.
