The 1903 U.S. Open was the ninth U.S. Open, held June 26–29 at Baltusrol Golf Club in Springfield, New Jersey, west of New York City. Willie Anderson won his second U.S. Open title in a playoff over David Brown. The championship was played on the original course at Baltusrol, now known as the Old Course, which no longer exists. Anderson became the first golfer to win the U.S. Open twice. This win was the first in a run of three consecutive Open titles, a feat unmatched before or since in tournament history. Anderson's four U.S. Open titles remains tied for the tournament record.
