Nearly two decades after its introduction to the world, Grey’s Anatomy’s cast of actors and their characters bring back the hit medical drama in 2024's Season 20.

Grey's Anatomy ranks as the longest-running scripted primetime show on ABC, having rated impressively high since it first arrived on the small screen in 2005.

Renewed for Season 20 in February 2023, Variety also confirmed that Season 19 was ABC's highest-ranked show amongst adults in the 18-49 range. After being delayed by the writers' and actors' strikes, Grey's Anatomy Season 20's first episode premiered on ABC on March 14.

Every Character & Actor in Grey's Anatomy Season 20

Ahead is a list of every actor in the cast of Grey's Anatomy Season 20 along with the characters they play:

Harry Shum Jr. quickly makes his mark on Grey's Anatomy as he takes on the role of Dr. Benson “Blue” Kwan, an intern who stars working at Grey Sloan in Season 19.

Throughout his time in the last season, though, he and fellow intern Dr. Millin show some sparks as a relationship begins budding.

Kwan is part of the cast of 2018's hit film Crazy Rich Asians along with 90 episodes of work in Glee. He is also heard in a voiceover role in 2024's Kung Fu Panda 4.
