Tiger Woods holds the record for the largest margin of victory in a major championship, winning the 2000 U.S. Open by 15 strokes.
Played at Pebble Beach Golf Links, the 2000 U.S. Open was Woods's first U.S. Open victory and his third major title. He finished at 12-under-par 272, while Ernie Els and Miguel Ángel Jiménez tied for second at 3-over-par 287. Woods was the only player to finish under par.
The victory surpassed Old Tom Morris's 13-stroke margin at the 1862 Open Championship. Morris's record was achieved over 36 holes, while Woods's 15-stroke margin came in the modern 72-hole stroke-play format. That distinction sometimes causes confusion when historical major records are compared.
Woods's performance was dominant from the start: he opened with a 65, built a ten-stroke lead after 54 holes, and closed with a bogey-free 67. Later in 2000, he won the Open Championship and PGA Championship as part of a remarkable four-major streak.
