Daniel Leonard Ozark, born Orzechowski (November 26, 1923 – May 7, 2009), was an American coach and manager in Major League Baseball. As manager of the Philadelphia Phillies (1973–August 31, 1979), Ozark led the Phils to three consecutive National League East Division championships (1976–77–78), but each year his team fell in the National League Championship Series. He was the fourth manager to reach the Championship Series (National or American) in three straight seasons and the first to lose all of them (Whitey Herzog would join him on the same day as Ozark).
