The 2025 Atlantic Coast Conference women's soccer tournament, known as the Ally ACC Women’s Soccer Championship for sponsorship reasons, was the postseason women's soccer tournament for the Atlantic Coast Conference, held November 2-9, 2025. The five-match tournament took place at campus sites for the two quarterfinals and First Horizon Stadium at WakeMed Soccer Park in Cary, North Carolina for the semifinals and final. The higher seed hosted the campus site matches. The six-team single-elimination tournament consisted of three rounds based on seeding from regular season conference play. The Florida State Seminoles were the five-time defending champions. The Seminoles were unable to defend their title, as they lost in a penalty shoot-out in the quarterfinals. The final was contested by the first seed Stanford and second seed Notre Dame, who were also the first and second nationally ranked teams in the United Soccer Coaches poll at the time of the match. The teams played to a 2–2 draw, and Stanford prevailed 5–4 in the ensuing penalty shoot-out. This was Stanford's first ACC tournament title after they joined the conference last year, and also the first ACC title for head coach Paul Ratcliffe. As tournament champions, Stanford earned the ACC's automatic berth into the 2025 NCAA Division I women's soccer tournament.
