Margaret "Maggie" Pierce, M.D., F.A.C.S., is a fictional character from the medical drama Grey's Anatomy, which airs on the American Broadcasting Company (ABC), portrayed by Kelly McCreary. Created by series producer Shonda Rhimes, Maggie first appeared in the penultimate episode of the show's tenth season and was promoted to a series regular by the eleventh season's eleventh episode. Her character is revealed to be the biological daughter of Richard Webber (James Pickens Jr.) and Ellis Grey (Kate Burton), making her the half-sister of series protagonist Meredith Grey (Ellen Pompeo).

Maggie is characterized as "perky" and "chatty" but also extremely focused on her academic career. She was a child prodigy, having graduated from medical school at the remarkably young age of 19, and by the time she is introduced in the series, she has become the head of the cardiothoracic surgery department at just 27 years old.^[1]
