The 2023 San Francisco Giants season was the 141st season for the franchise in Major League Baseball, their 66th year in San Francisco, and their 24th at Oracle Park. The team was managed by Gabe Kapler until September where with three games remaining, the Giants relieved Kapler of his duties. The San Francisco Giants drew an average home attendance of 30,866 in 81 home games in the 2023 MLB season, the 17th highest in the league. The total attendance was 2,500,153.

The Giants faced challenges at the beginning of the season, posting an 11–17 record in their initial 28 games. Nevertheless, they managed to rebound, achieving a 54–41 record and securing a winning record of 61–49. Despite their initial resurgence, they could not avoid a late-season collapse, finishing the remaining games at 18–34. Consequently, they were unable to surpass their 81–81 record from the previous season, ending with a losing record of 79–83. This outcome eliminated them from playoff contention for the second consecutive season.
