2012 HP Open – Singles

Marion Bartoli was the defending champion, but chose not to compete.
Heather Watson won the title after a marathon 3 hour 12 minute battle with Chang Kai-chen. The match saw Watson hold match point before Chang came back and won the second set. Chang went up a break and had multiple match points at 5–4 before Watson broke and won a final-set tiebreak. Watson won by a score of 7–5, 5–7, 7–6^(7–4). That meant for the first time in 25-year history, a British female won an WTA tournament.
