Stamina (1905–1930) was an American Thoroughbred racehorse that was the historical top 2-year-old and 3-year-old filly in the United States in 1907 and 1908, respectively. Through the 1907 racing season, she was trained by future Hall of Fame inductee, John W. Rogers. On the death of Rogers in early 1908, another future Hall of Fame inductee, Jack Joyner, took over.
