Taylor Fritz defeated Alexander Zverev in the final, 6–3, 7–6(7–0) to win the singles tennis title at the 2025 Stuttgart Open.[1] He won the title without losing a set or having his serve broken during the tournament. It was Fritz's fourth grass court title, and ninth ATP Tour singles title overall.

Jack Draper was the reigning champion,[2] but did not participate this year.

At 17 years and eight months old, Justin Engel was the second-youngest player since 1990 to win a tour-level match (excluding Davis Cup) on three surfaces, after Rafael Nadal.[3] He became the youngest quarterfinalist in the tournament's history and the youngest at any grass-court tournament since Boris Becker at the 1985 Wimbledon Championships.[4]
