Miranda Bailey 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 has been portrayed by actress Chandra Wilson since the show's inception in 2005. Introduced as a resident in general surgery at the fictional Seattle Grace Hospital, Bailey worked her way up to the attending physician level, while her relationship with the five surgical interns she was in charge of - Meredith Grey (Ellen Pompeo), Cristina Yang (Sandra Oh), Izzie Stevens (Katherine Heigl), George O'Malley (T.R. Knight) and Alex Karev (Justin Chambers) - formed a focal point at the beginning of the series.

Her colleagues refer to her as "The Nazi" because of her tough personality and blunt attitude. Although often harsh with her interns, she has been shown to provide both support and advice. She married Tucker Jones in 1995, but their marriage encountered difficulties in 2007, due to her commitments as both a parent to son Tuck and to her career as a surgeon. Miranda Bailey is a Wellesley College graduate.
