2025 Seattle Storm season

The 2025 season for the Seattle Storm of the Women's National Basketball Association (WNBA) will be their 26th season as a franchise. It will be the fourth full season under head coach Noelle Quinn.

The 2025 season will consist of 44 regular season games played against 12 other teams. The WNBA increased its number of regular season games and announced that the 2025 WNBA Finals would be a best-of-seven series. The WNBA players' union announced on October 21, 2024, that they had opted out of the collective bargaining agreement (CBA) in place with the league, which expires at the end of the 2025 season.

In November 2024, the Storm's ownership hired a law firm to investigate allegations of player mistreatment by the coaching staff. The Storm announced there were no violations found as a result of the investigation. Shortly after the results were published, it was announced that Jewell Loyd had requested a trade.

The Storm did not have any players taken during the expansion draft held for the Golden State Valkyries on December 6, 2024.

On May 3, 2025, the Storm announced that newly signed forward, Katie Lou Samuelson, sustained a right ACL tear during practice on May 1.

In addition to their preseason match-up against Connecticut on May 4, the Storm also had a closed scrimmage versus Los Angeles on May 10 at Pauley Pavilion.

On June 4, 2025, it was reported that Li Yueru made a request to be traded. The following day after the Storm's practice, Li explained her request was due to her desire for playing time and stated, "I just want to play...I came to America only for one reason—just that I want to play basketball." She was traded to the Dallas Wings on June 14 in exchange for draft picks.
