The 1998 Masters Tournament was the 62nd Masters Tournament, held from April 9–12 at Augusta National Golf Club. Mark O'Meara won his first major championship with a 20-foot (6 m) birdie putt on the final hole to win by one stroke over runners-up David Duval and Fred Couples. O'Meara birdied three of the final four holes to shoot a final round 67 (−5).
In one of the most remarkable performances of his career, Jack Nicklaus tied for sixth place at the age of 58. His final round 68 (−4) yielded a 283 (−5), the lowest 72-hole score by a player over 50 in the Masters. Nicklaus was in contention for the title until well into the back nine holes in the final round. It was his last serious run for a major championship, 12 years after his victory at the 1986 Masters. Another former champion Gary Player became the oldest player ever to make the cut at the Masters at the age of 62.
In his first Masters, David Toms shot a 29 (−7) on the back nine on Sunday, en route to a 64 (−8). He had six consecutive birdies on holes 12–17.
O'Meara's win came in his 15th attempt at Augusta, setting a record for appearances before a victory. He had previously been considered one of the best players to never win a major. Later in July, he won the Open Championship and earned PGA Tour Player of the Year honors for 1998.
