João Fonseca defeated Alejandro Davidovich Fokina in the final, 6–3, 6–4 to win the singles tennis title at the 2025 Swiss Indoors.[1] It was his second ATP Tour title and first ATP 500 title.[2] Fonseca was the second-youngest champion in tournament history, after Jim Courier in 1989, and the third-youngest ATP 500 champion since the current format was introduced in 2009. Fonseca was also the first Brazilian to win an ATP 500 tournament since Gustavo Kuerten in 2001.

Giovanni Mpetshi Perricard was the defending champion,[3] but lost in the first round to Fonseca.[4]
