The Seattle Sounders FC, under head coach Brian Schmetzer, celebrated a historic 2025 season by capturing their first-ever Leagues Cup title with a dominant 3–0 victory over Inter Miami CF at Lumen Field. The club also competed in the FIFA Club World Cup and CONCACAF Champions Cup, though they failed to advance past the group stage of the former. In MLS regular-season play, the Sounders finished fifth in the Western Conference and qualified for the playoffs, but were eliminated in the first round by Minnesota United FC after a penalty shootout. The roster saw major changes, including a trade for forward Jesús Ferreira and the signing of Paul Arriola, while bidding farewell to franchise legend Raúl Ruidíaz, the team's all-time leading MLS scorer. Across all competitions, the club posted a 23-13-14 record, with Danny Musovski leading the squad with 18 goals and an average home attendance of nearly 31,000. This marked the team's 17th season in MLS and the 42nd for a professional Sounders franchise, which originally began in 1974.
