The 2012 Qatar Airways Tournament of Champions was a singles-only tennis tournament that was played on indoor hard courts in Sofia. It was the fourth edition of the tournament and was part of the 2012 WTA Tour. The 2012 edition was the first held in Sofia, having been relocated from Bali, where the tournament was held for the previous three years and called the Commonwealth Bank Tournament of Champions. The tournament was played between October 30 and November 4. Ana Ivanovic did not defend her title this year for two reasons: She did not win, or reach, a single final this year in order to gain direct acceptance, and she did not receive a wild card due to her participation in the 2012 Fed Cup finals.
