Clark Calvin Griffith (November 20, 1869 – October 27, 1955, ), nicknamed "the Old Fox", was an American Major League Baseball (MLB) pitcher, manager and team owner. He began his MLB playing career with the St. Louis Browns (1891), Boston Reds (1891), and Chicago Colts/Orphans (1893–1900). He then served as player-manager for the Chicago White Stockings (1901–1902) and New York Highlanders (1903–1907).

He retired as a player after the 1907 season, remaining manager of the Highlanders in 1908. He managed the Cincinnati Reds (1909–1911) and Washington Senators (1912–1920), making some appearances as a player with both teams. He owned the Senators from 1920 until his death in 1955. Sometimes known for being a thrifty executive, Griffith is also remembered for attracting talented players from the National League to play for the upstart American League when the Junior Circuit was in its infancy. Griffith was elected to the National Baseball Hall of Fame in 1946.
