The 2023 San Diego Padres season was the 55th season of the San Diego Padres franchise. The Padres played their home games at Petco Park as members of Major League Baseball's National League West. The Padres had a record of 82–80. The Padres drew an average home attendance of 40,389 in 81 home games in the 2023 MLB season, the 3rd highest in the league.

The Padres were coming off a season in which they made it to the 2022 NLCS and an offseason in which they signed prized free agent Xander Bogaerts to an 11-year deal. Furthermore, the Padres anticipated that their star shortstop and right fielder, Fernando Tatis Jr., would return to the team on April 20 after missing the entire 2022 season due to an injury and an 80-game suspension. Given the Padres' performance in 2022 and their reinforcements for 2023, the 2023 Padres entered the season with high expectations. In fact, several observers, analysts, and pundits predicted that the Padres would win the division over the perennial favorite Los Angeles Dodgers, who had won the NL West in nine of the previous ten seasons. The Padres, however, failed to meet the lofty expectations. They disappointingly hovered around or below a .500 winning percentage for much of the season, and despite a strong September, the Padres missed the playoffs.

On July 22, they beat the Detroit Tigers for their 4,000th win in franchise history. This was the Padres' final season under owner Peter Seidler. Seidler died on November 14 at the age of 63.
