Bellatrix Lestrange (née Black) is a fictional character in the Harry Potter book series written by J. K. Rowling. She evolved from an unnamed periphery character in Harry Potter and the Goblet of Fire into a major antagonist in subsequent novels. In the final instalment of the story, Rowling established her as Lord Voldemort's "last, best lieutenant". Bellatrix was the first female Death Eater introduced in the books, and remained the only woman explicitly identified as such.
