In House M.D., which actress plays Dr. Allison Cameron?

Jennifer Morrison plays Dr. Allison Cameron in House M.D.

Cameron is an immunologist and one of the three doctors selected for House’s original diagnostic fellowship team. Her empathy and concern for patients often contrast with House’s blunt, risk-taking approach. The character’s professional and personal relationships, especially with Chase and House, form recurring parts of the early series.

Morrison is an American actress, director, and producer. House M.D. was one of her prominent early television roles, and she later became widely known for playing Emma Swan in Once Upon a Time. In House, her performance helped define Cameron as an idealistic physician whose compassion sometimes leads her into difficult ethical decisions.

Lisa Edelstein played Lisa Cuddy, while Olivia Wilde played Remy “Thirteen” Hadley. Those characters are also major women in the series, which can make the cast easy to confuse, but neither actress portrayed Allison Cameron.
