Eleven (Millie Bobby Brown) and the other memorable residents of Hawkins, Indiana will say goodbye when Stranger Things season 5 premieres on Netflix in 2025. There's a lot that needs to happen, including the main characters hopefully preventing more evil from infiltrating their town (and the world). If The Party is successful, then maybe Eleven and her friends can think about a future that doesn't involve the Upside Down, which fans have theories about.
