Kate Walsh is set to return to Grey’s Anatomy for Season 22, adding another chapter to her long-running connection with the medical drama. A new report confirms that Walsh will once again appear as Dr. Addison Montgomery, a role she first stepped into during the show’s earliest episodes. This marks her latest reentry into the series after recurring stints in Seasons 18 and 19, though the extent of her Season 22 involvement has not yet been detailed. That uncertainty is the catch: fans will see Dr. Montgomery again, but it remains unclear whether her role will be substantial or limited to a brief appearance.
Walsh and her character have been intertwined with the Grey’s Anatomy universe since Season 1, when Dr. Montgomery appeared in the show’s ninth episode. Her direct, often uncompromising medical style quickly made an impression, leading to Walsh becoming a series regular for Seasons 2 and 3. After departing the main cast, she continued to return periodically in guest roles from Seasons 4 through 8 and more recently in Seasons 18 and 19. While she is not among the show’s longest-tenured cast members, Addison has remained one of its most recognizable figures, remembered for both her professional storylines and personal arcs, including her relationship with Dr. Jake Reilly.
The news of Walsh’s return arrives during a milestone year. Grey’s Anatomy reaches its twentieth anniversary in 2025, a reminder of how many prominent actors have passed through the series. Sandra Oh, who played Dr. Cristina Yang for its first ten seasons, remains one of the show’s most influential alumni and has not yet returned since her departure. Patrick Dempsey, whose Dr. Derek Shepherd was central to the series for over a decade, left after Season 11 but briefly returned in Season 17. Only a small group of original cast members—Ellen Pompeo as Meredith Grey, Chandra Wilson as Miranda Bailey, and James Pickens Jr. as Richard Webber—have been continuously involved since the beginning.
As Grey’s Anatomy enters another season, the return of a familiar character underscores the show’s ongoing balance between honoring its history and adapting to new eras. What remains to be seen is how Season 22 will use Addison Montgomery, a character whose intermittent appearances continue to shape the show’s evolving legacy.
