In House M.D., what is the name of House’s former lover Stacy Warner?

House’s former lover in House M.D. is Stacy Warner.

Stacy is an attorney who was romantically involved with Gregory House before the series begins. Their relationship ended after House’s severe leg infarction and the medical decisions surrounding his treatment. She later returns to Princeton-Plainsboro as a lawyer connected to a patient, reopening unresolved feelings between them.

The character is important because she knew House before his pain and disability reshaped his life. Her return reveals a more vulnerable side of him and helps explain why he resists emotional intimacy. Stacy is played by Sela Ward and appears primarily in the show’s first two seasons.

Stacy Warner is not the same character as Amber Volakis, House’s colleague and Wilson’s partner, or Dominika Petrova, whom House marries for immigration reasons. Allison Cameron is another colleague and former romantic connection, but she is not House’s former lover from before the series begins.
