The 1971 Open Championship was the 100th Open Championship, played 7–10 July at Royal Birkdale Golf Club in Southport, England. Lee Trevino won the first of his consecutive Open Championships, one stroke ahead of Lu Liang-Huan. It was the third of his six major titles and his second consecutive; he won the U.S. Open less than a month earlier in a playoff over Jack Nicklaus.
