The 1966 Major League Baseball All-Star Game was the 37th midseason exhibition between the all-stars of the American League (AL) and the National League (NL), the two leagues comprising Major League Baseball. The game was played on July 12, 1966, at then-new Busch Memorial Stadium in St. Louis, Missouri. The 10-inning contest – which was played on a memorably hot and humid afternoon in St. Louis, with a game-time temperature of 103 °F (39 °C) – resulted in a 2–1 victory for the NL.
