The Latonia Derby was an American Thoroughbred horse race run annually from 1883 through 1937 at Latonia Race Track in Latonia, Kentucky. Open to three-year-old horses, for its first 52 years the Latonia Derby was contested at a mile and a half then in 1935 the distance was shortened to a mile and a quarter. It was run as the Hindoo Stakes from inception in 1883 to 1886 in honor of the Kentucky-bred U.S. Racing Hall of Fame horse, Hindoo. The race usually attracted the Kentucky Derby winner; it became so popular that in 1912 a motion picture was made by Independent Motion Picture Co. entitled Winning the Latonia Derby, featuring silent film star King Baggot.
