The 2025 UC Davis Aggies football team represented the University of California, Davis during the 2025 NCAA Division I FCS football season as a member of the Big Sky Conference. They were led by second-year head coach Tim Plough and played their home games at UC Davis Health Stadium in Davis, California. It was the Aggies' 106th season overall, and 14th in the Big Sky.
UC Davis finished the regular season 8âÂÂ3 and received a bye during the first week of the FCS playoffs due to their No. 11 (No.8 by the playoff committee) ranking. After defeating the Rhode Island Rams in the Second Round at home, the Aggies would fall to eventual championship runner-ups Illinois State in the Quarterfinals, also at home. Due to the FCS Committee's ranking of the Aggies prior to the start of the playoffs, UC Davis was able to host two consecutive playoff games for the first time since joining Division I FCS in 2003, and the first time hosting a Quarterfinal since 2001.
UC Davis saw record average attendance this season, with an average of 12,991 fans per a game alongside the new stadium record of 17,217, which sets the highest attendance out of all of UC Davis's home venues. This season also saw the first time a linear ESPN channel had been hosted at a UC Davis home game, with the Second Round game against Rhose Island being shown.
On July 17, 2025, during the virtual Big Sky Kickoff, the Aggies were predicted to finish second in the Big Sky by the coaches and third by the media.
On August 23, UC Davis was set to play in the FCS Kickoff in their first of three nationally televised games this season. With just 7:46 left in the fourth quarter, and Mercer having the ball with a 1st-and-10 at the UC Davis 48-yard line, the game was suspended due to lightning. In the early morning hours of August 24, it was announced that the game would not resume, and that both teams had agreed to declare it a no contest despite the Aggies leading 23âÂÂ17. â¡New UC Davis Health Stadium attendance record.
