Jan-Lennard Struff defeated Taylor Fritz in the final, 7–5, 6–3 to win the singles tennis title at the 2024 Bavarian International Tennis Championships. It was Struff's first career ATP Tour singles title, and he did not drop a set en route. Aged 33 years and 11 months old, Struff became the oldest first-time ATP Tour singles champion since Paolo Lorenzi at the 2016 Austrian Open, as well as becoming the third-oldest first-time ATP Tour champion (after Lorenzi and Victor Estrella Burgos) since its establishment in 1990.[1]
Holger Rune was the two-time defending champion, [2] but lost in the semifinals to Struff.
The top four seeds received a bye into the second round.
