Harry O'Casey was a recurring character on Xena: Warrior Princess. He was a dentist, who was romantically involved with Annie Day and, later, Mattie Merrill. When Annie thought that she was the reincarnation of Xena, Harry reluctantly accompanied her to a clinic where Mattie was conducting past-life regression therapy. When a distraught Annie realized that she was actually the reincarnation of Joxer, Harry and Mattie put themselves under and discovered that Harry was actually Xena, while Mattie was Gabrielle. Harry/Xena discovered that Mattie/Gabrielle had been tricked by none other than Ares, who wanted Xena back, even if she was in the wrong body. After Harry defeated Ares, Annie discreetly slipped away so that Harry and Mattie could be together.
Two years later, Harry and Mattie were returning from their honeymoon (visiting their old battlegrounds in Greece) when Annie informed them a marriage contract between Xena and Ares had been uncovered. Although Harry managed to destroy the contract and defeat Ares yet again, the god managed to switch Xena and Joxer's souls, rendering Harry Joxer once again. Then Xena Gabrielle and Joxer were reunited once again.
- The character was only referred to as "Harry" onscreen. The last name "O'Casey" comes from production material for the episode.
