The 2005 San Diego Padres season was the 37th season for the San Diego Padres. For the first time since 1998, the Padres qualified for the postseason after five straight losing seasons. The 2005 team is noted as having one of the weakest records among any team to qualify for the postseason, finishing 82–80, which was tied with the 1973 New York Mets for the fewest wins ever in a non-shortened year since Major League Baseball expanded to a 162-game season in 1961, and the fewest of any team since 1885 (the record was eclipsed by the 2026 Houston Astros). They also had a run differential of –42, the second lowest of any team ever to make the postseason and the lowest for a division champion; their best month of the season was in May by going 22–6 with a +43 differential while the rest of the season saw them outscored by 85 runs.
The National League West was weak in 2005, with all teams finishing below the .500 mark except for the San Diego Padres, who only finished two games above the .500 mark. The closest team, the Arizona Diamondbacks, were five games back. Three teams in the Eastern Division finished with better records than San Diego but failed to qualify for the playoffs, such as the Philadelphia Phillies, who won 88 games and won all six of their games against the Padres.
There had been some speculation that the Padres would be the first team in MLB history to win a division and finish below .500, but their victory over the Los Angeles Dodgers on September 30 gave them their 81st victory, guaranteeing a split record. They were swept in three games by the St. Louis Cardinals in the NLDS.
Offseason December 22, 2004: Mark Sweeney was signed as a free agent with the San Diego Padres.
