The title of American Champion Older Dirt Male Horse is an American Thoroughbred horse racing honor awarded annually to a stallion or gelding, four years old and up, for performances on dirt and main track racing surfaces. In 1971, it became part of the Eclipse Awards program as the award for Champion Older Male Horse. Champions from 1887 through 1935 were selected retrospectively by a panel of experts as published by The Blood-Horse magazine.
