The 2025 WNBA playoffs ran from September 14 to October 10, 2025, culminating in the Las Vegas Aces winning their third championship. A historic milestone was achieved by the Golden State Valkyries, who became the first expansion team in WNBA history to reach the postseason in their inaugural season. The playoffs also introduced a major format change, as the WNBA Finals adopted a best-of-seven series for the first time in league history. In the first round, the top-seeded Minnesota Lynx faced the eighth-seeded Valkyries, while the Connecticut Sun missed the playoffs, snapping their eight-season postseason streak. Additionally, the Aces extended their longest active postseason appearance streak to seven consecutive years.
