Which golfer holds the record for the most men's major championship victories?

Jack Nicklaus holds the record for the most men's major championship victories, with 18 wins.

Nicklaus won the four professional majors—the Masters Tournament, U.S. Open, The Open Championship and PGA Championship—between 1962 and 1986. His total includes six Masters victories, four U.S. Opens, three Open Championships and five PGA Championships.

His first major came at the 1962 U.S. Open, where he defeated Arnold Palmer in a playoff. His final major was the 1986 Masters, won at age 46 with a memorable final-round 65. That victory made him the oldest Masters champion at the time and remains one of golf's defining finishes.

Tiger Woods ranks second with 15 men's majors, while Walter Hagen won 11 and Gary Player won nine. Nicklaus is also one of the small group of golfers to complete the career Grand Slam by winning all four professional majors. His record is distinct from total professional tournament victories or senior-major championships.
