Premiering in 2005, *Grey’s Anatomy* stands as one of the most successful and longest-running medical dramas in history. Over more than two decades on air, the series has seen a host of beloved characters bid farewell—departures ranging from emotional storylines to controversial behind-the-scenes decisions. Here are 15 key actors who left *Grey’s Anatomy* and the legacies they left behind.
1. Sandra Oh (Cristina Yang)
Sandra Oh was one of the show’s most beloved stars, playing Dr. Cristina Yang. After 10 seasons, she left the series in 2014 to pursue new acting challenges. She subsequently achieved massive success with *Killing Eve*, garnering numerous prestigious nominations and awards.
2. Patrick Dempsey (Derek Shepherd)
Patrick Dempsey—affectionately known to fans as “McDreamy”—left the show in Season 11 when his character, Derek Shepherd, died in a car accident. This decision shocked audiences worldwide. He later made a special return appearance in Season 17.
3. Katherine Heigl (Izzie Stevens)
Katherine Heigl parted ways with the show after Season 6 amidst rumors of conflict and creative differences.

4. Justin Chambers (Alex Karev)
Justin Chambers made a surprise exit from the series after 16 seasons. His character, Alex Karev, was written out by reuniting with Izzie Stevens and their two children, rather than appearing on-screen for the farewell.
5. T.R. Knight (George O’Malley)
George O’Malley was one of the first characters to move viewers to tears when he sacrificed his life in a bus accident during Season 5. T.R. Knight stated that he left the show because he felt his character had run out of narrative potential and due to differences regarding creative direction.
6. Isaiah Washington (Preston Burke)
Isaiah Washington was written out of the show after Season 3 following behind-the-scenes controversy. However, he returned for a Season 10 episode to bring closure to Cristina Yang’s storyline.
7. Eric Dane (Mark Sloan)

After more than a decade with the show, Sara Ramirez departed *Grey’s Anatomy* at the end of Season 12. The actress subsequently took on various other projects, including *And Just Like That…*.
10. Jessica Capshaw (Arizona Robbins)
Jessica Capshaw left the series after Season 14 when the production team decided to streamline the main cast. Arizona Robbins’ departure was met with disappointment by many fans.

14. Kim Raver (Teddy Altman)
Kim Raver previously left the series after Season 8 due to a shift in production direction. She returned in a recurring role in Season 14 before being promoted back to series regular starting in Season 15.
15. Ellen Pompeo (Meredith Grey)
While she has not left the series entirely, Ellen Pompeo stepped back from her role as a full-time series regular starting in Season 19 to reduce her workload. She continues to provide voiceovers, serve as an executive producer, and appear in select episodes—marking a significant transition after nearly two decades of portraying Meredith Grey.
The Legacy of a Legendary Cast
Cast turnover has been an integral part of *Grey’s Anatomy*. Each departure creates memorable moments, helping the series constantly reinvent itself across generations of characters. To date, only a few veterans—such as Meredith Grey (who makes infrequent appearances), Miranda Bailey, and Richard Webber—remain with the franchise, which has spanned more than two decades.
