The Commonwealth Handicap was an American Thoroughbred horse race run annually from 1903 through 1910 at Sheepshead Bay Race Track in Sheepshead Bay, New York. Open to horses age three and older, it was run on dirt over a distance of 1¼ miles on dirt. It was raced in its first year as the "Suburban Renewal Handicap" having been created as a sequel to Suburban Handicap, the most important race in New York at the time for horses aged three and older. In a July 1, 1906 review of upcoming races, the Daily Racing Form referred to the Commonwealth Handicap as a "highly important" race.
