The 2023 U.S. Open is the first major championship held at The Los Angeles Country Club and will be contested on the North Course. The first edition of the Los Angeles Open, now known as The Genesis Invitational, was held at LACC (North) in 1926, and the event has been held there a total of five times (1926, 1934, 1935, 1936, 1940). The last major championship played in the Los Angeles area was the 1995 PGA Championship, held at The Riviera Country Club, the host venue of The Genesis Invitational.

2021 U.S. Open winner Jon Rahm enters the week as the FedExCup leader with four wins this season, including the Masters Tournament. With a win this week, Rahm would become the first player to win five times in a season since Justin Thomas in 2016-17 and the first to win multiple majors in the same year since Jordan Spieth in 2015 (Masters, U.S. Open). With 3,042 FedExCup points so far this season, Rahm has the fifth-highest total in a single FedExCup Regular Season since the inception of the FedExCup in 2007. He is 17 points behind No. 4 (Tiger Woods/2013) and 1,127 behind No. 1 (Jordan Spieth/2014-15).

The 2011 U.S. Open winner and reigning FedEx Cup Champion Rory McIlroyhas won four majors (2011 U.S. Open, 2012 PGA Championship, 2014 Open Championship, 2014 PGA Championship) but none since the start of the 2014-15 season. McIlroy has 18 Top-10s in majors since his most recent title, the most of any player in that span.

McIlroy is making his 48th start in a major and 33rd since winning the 2014 PGA Championship.

There are four players in the top 10 of the Official World Golf Ranking that have not won a major: No. 4 Patrick Cantlay, No. 5 Viktor Hovland, No. 6 Xander Schauffele and No. 7 Max Homa. Those four players have combined for 25 PGA Tour titles and have all won at least twice since the start of the 2021-22 season.
