A career Grand Slam in golf is achieved when a player wins each of the four major championships at least once during their professional career. These four majors are:
- The Masters Tournament
- The PGA Championship
- The U.S. Open
- The Open Championship (British Open)
Winning all four majors in the same calendar year is called a "calendar-year Grand Slam," which is extremely rare and has only been accomplished by Bobby Jones in 1930 (with a different set of majors at that time). The career Grand Slam, by contrast, can be completed over multiple years. Only six male golfers in the modern era have completed the career Grand Slam:
- Gene Sarazen
- Ben Hogan
- Gary Player
- Jack Nicklaus
- Tiger Woods
- Rory McIlroy (who completed it by winning the 2025 Masters)
Tiger Woods also achieved a unique feat called the "Tiger Slam," holding all four major titles simultaneously but not in the same calendar year (2000–2001)
. In summary, the career Grand Slam is one of golf's greatest achievements, marking a player's victory in all four majors at least once over their career.
