The 1964 Masters Tournament was the 28th Masters Tournament, held April 9–12 at Augusta National Golf Club in Augusta, Georgia. A field of 96 players entered the tournament and 48 made the 36-hole cut at 148 (+4).
Arnold Palmer, age 34, opened with three rounds in the 60s and led by five strokes after 54 holes at 206 (−10). He carded a final round of 70 on Sunday to win by six strokes to become the first four-time winner of the Masters. It was his seventh and final major victory.
Craig Wood, the 1941 champion, played in his final Masters, but withdrew before completing the first round. Prior to his win at Augusta, he was the runner-up in the first two Masters in 1934 and 1935.
