King James (foaled 1905 in Kentucky) was an American Thoroughbred racehorse. Bred by one of America's most important breeders, John E. Madden, he was the son of 1898 Kentucky Derby winner Plaudit. Although burdened by a bad stride that limited his racing ability, King James raced for five years, won a number of top events, and is acknowledged as the historical American Champion Older Male Horse of 1909.
