Alexandra Caroline "Lexie" Grey,M.D. is a fictional character from the medical drama television series Grey's Anatomy, which airs on ABC in the United States. The character was created by series' producer Shonda Rhimes and was portrayed by actress Chyler Leigh from the third through eighth seasons. She was introduced as a surgical intern in season three. Serving as Meredith Grey (Ellen Pompeo)'s half sister, she transferred to the fictional Seattle Grace Hospital, after her mother's sudden death. Eventually named a surgical resident, the character was originally contracted to appear for a multi-episode story arc, but received star billing in the fourth season.

The character's focal storyline involved a romantic relationship with plastic surgeon Mark Sloan (Eric Dane). She sustained life-threatening injuries after an aviation accident, in the eighth-season finale, which ultimately ended in her death. The character's death resulted in mixed critical feedback and the reason given for the departure was Leigh's desire to spend more time with her family. Rhimes has characterized Lexie as being a dork, as well as having issues with saying how she feels. Leigh has been moderately well received by critics, and was among the cast to receive a Screen Actors Guild Award nomination for Outstanding Performance by an Ensemble in a Drama Series in 2007.
