Six male golfers have completed the career Grand Slam in golf, meaning they have won all four major championships (The Masters, U.S. Open, The Open Championship, and PGA Championship) at least once during their careers. These golfers are:

• Gene Sarazen
• Ben Hogan
• Gary Player
• Jack Nicklaus
• Tiger Woods
• Rory McIlroy (completed in 2025 with his Masters win)

No golfer has ever won all four majors in a single calendar year (a "calendar Grand Slam") in the modern era. Jack Nicklaus and Tiger Woods have each completed the career Grand Slam three times, the most among all players

. Thus, the total number of golfers who have achieved the career Grand Slam is six.
