Alexander Bublik defeated Daniil Medvedev in the final, 6–3, 7–6(7–4) to win the singles tennis title at the 2025 Halle Open. It was his second Halle title (after 2023) and fifth ATP Tour singles title overall.
Jannik Sinner was the defending champion, but lost in the second round to Bublik. The defeat ended Sinner's streak of 66 consecutive wins against players ranked outside of the world's top 20 (dating back to the 2023 Cincinnati Open), as well as his streak of 19 consecutive tournament quarterfinals.
