What is Lexie Grey's full name on Grey's Anatomy?

What is Lexie Grey's full name on Grey's Anatomy? The answer is Alexandra Caroline Grey.

Lexie Grey is the familiar name of Alexandra Caroline Grey, the surgical trainee who becomes one of the show's prominent younger doctors. She is introduced as Meredith Grey's paternal half-sister and joins Seattle Grace after the sudden death of her mother, Susan Grey.

Lexie's first name is Alexandra, not Alexis or “Lexandra.” “Lexie” is a nickname formed from Alexandra, while Caroline is her middle name. The character is portrayed by Chyler Leigh and first appears near the end of season 3 before becoming a series regular in season 4.

Lexie is written as exceptionally intelligent and emotionally earnest. Her eidetic memory helps her absorb medical information quickly and leads to the nickname “Lexipedia.” She progresses from surgical intern to resident, develops important relationships with Meredith and Mark Sloan, and dies after the season 8 plane crash. Her memory is later honored in the hospital's name, Grey Sloan Memorial.
