Imp (1894–1909) was a pure black Thoroughbred racing filly with a white, diamond-shaped star between her eyes.

[1] Owned and bred by Daniel R. Harness of Chillicothe, Ohio, and trained by both Charles E. Brossman and Peter Wimmer (when she was seven), Imp's male line of descent was the great Eclipse.

Imp, nicknamed "My Coal Black Lady" after a popular song of the day, was a bit of a homely-looking thing, the daughter of parents who each raced only once.

In her fourth season she was shipped to New York to challenge the big-name horses in the Suburban Handicap.

Extremely popular in the Gay Nineties, she retired at seven years of age, having set records at 1 1/16, 1¼, 1½ and 1¾ mile.

More than five decades after her death, Imp was inducted into the National Museum of Racing and Hall of Fame in Saratoga Springs, New York in 1965.
