Tomáš Berdych was the defending champion, but lost in the second round to Robin Söderling.
Roger Federer won in the final 6–3, 6–4, against Philipp Kohlschreiber.[1] It was Federer's record-extending fifth singles title in Halle, after previously winning four consecutive titles (2003–06) and skipping the tournament in 2007 due to fatigue.[2] He did not lose a single set in the entire tournament and, in the process, extended his record grass court winning streak to 59 matches.[3]
