The United States Open Championship, commonly known as the U.S. Open, is the annual open national championship of golf in the United States. It is the third of the four men's major golf championships, and is on the official schedule of both the PGA Tour and the European Tour. Since 1898 the competition has been 72 holes of stroke play, with the winner being the player with the lowest total number of strokes. It is staged by the United States Golf Association (USGA) in mid-June, scheduled so that, if there are no weather delays, the final round is played on the third Sunday. The U.S. Open is staged at a variety of courses, set up in such a way that scoring is very difficult, with a premium placed on accurate driving. As of 2023, the U.S. Open awards a $20 million purse, the largest of all four major championships.
The U.S. Women's Open, one of 15 national golf championships conducted by the United States Golf Association (USGA), is the oldest of the LPGA Tour's five major championships, which includes the Chevron Championship, Women's PGA Championship, Women's Open Championship, and The Evian Championship.
The U.S. Senior Open is one of the five major championships in senior golf, introduced 44 years ago in 1980. It is administered by the United States Golf Association (USGA) and is recognized as a major championship by both the PGA Tour Champions and the European Senior Tour. The lower age limit was 55 in 1980, but it was lowered to 50 for the second edition in 1981, which is the standard limit for men's senior professional golf tournaments. By definition, the event is open to amateurs, but has been dominated by professionals; through 2022, all editions have been won by pros. Like other USGA championships, it has been played on many courses throughout the United States.

Women's professional senior golf is for female players aged 45 or 50 and above. The leading women's senior tour is the U.S.-based Legends Tour, which was founded in 2000. It has established a roster of two major championships. On the Legends Tour, the minimum age is 45, although with the USGA instituting the new U.S. Senior Women's Open in 2018, it chose a minimum age of 50. Also, the U.S. Senior Women's Open is played over four rounds, whereas the Senior LPGA Championship is played over three rounds. A golfer's performances can be quite variable from one round to the next, so playing an extra round increases the likelihood that the tournament will be won by leading players.
