Jack Nicklaus won 73 PGA Tour events.
That total places Nicklaus among the most successful players in PGA Tour history. His victories included 18 major championships: six Masters titles, four U.S. Opens, three Open Championships and five PGA Championships. The 73-win figure counts his recognized PGA Tour victories, not every professional tournament he won around the world.
Nicklaus’s first PGA Tour victory came at the 1962 U.S. Open, where he defeated Arnold Palmer in an 18-hole playoff. His final PGA Tour win was the 1986 Masters, one of golf’s most celebrated performances. At age 46, he closed with a 65 and made the famous fist-pump after his birdie putt on the 17th hole.
The main source of confusion is mixing career totals from different tours or counting all professional wins. Nicklaus had additional victories internationally and in senior competition, but the standard PGA Tour answer is 73. Sam Snead and Tiger Woods are credited with 82 PGA Tour wins each.
