The American Champion Steeplechase Horse is an American horse racing honor awarded as part of the Eclipse Award program since its inception in 1971. It is awarded annually to the top horse in steeplechase racing.

Flatterer is the only horse to win the award four times in a row, his last coming at age 7 in 1986. Lonesome Glory has won the Award five times, more than any other horse, and was the oldest ever when he won it for the final time at age 11.
