Elena Gilbert is a fictional character and protagonist from the novel series The Vampire Diaries. In the television series adaptation, set in the fictional town of Mystic Falls, she is portrayed by Nina Dobrev. In the books, Elena was popular, selfish and a "mean girl". However, the show's producers, Julie Plec and Kevin Williamson, felt that it wasn't the direction they wanted to go with their heroine in The Vampire Diaries television series. Instead, she became a nicer, relatable, and more of "the girl next door" type, until her life gets flipped upside down when she meets the Salvatore Brothers. In April 2015, Nina Dobrev announced that she would be departing the series after the sixth-season finale.

The Vampire Diaries is a young adult vampire fiction series of novels created by American author L. J. Smith. The story centers on Stefan Salvatore, a vampire, and his life.
