What medical specialty does Meredith Grey become an attending in?

Meredith Grey becomes an attending in general surgery.

Meredith begins Grey’s Anatomy as a surgical intern at Seattle Grace Hospital, later renamed Seattle Grace Mercy West and then Grey Sloan Memorial. She progresses through residency and chooses general surgery as her specialty, rather than following Derek Shepherd into neurosurgery or pursuing another surgical branch. After the Season 8 plane crash and the transition into Season 9, Meredith is established as an attending general surgeon.

Her career continues to develop: she later becomes Chief of General Surgery and eventually Chief of Surgery. The choice reflects a major part of her character arc. Meredith grows up under the shadow of her mother, Ellis Grey, a celebrated general surgeon, yet works to establish her own professional identity. Viewers sometimes confuse Meredith’s research in Alzheimer’s disease or her work with neurosurgeons with a change in specialty. Those storylines broaden her medical interests, but her core specialty remains general surgery.
