Ellie is a character in the video game series The Last of Us by Naughty Dog. She is portrayed by Ashley Johnson through motion capture and voice acting; in the television adaptation, she is portrayed by Bella Ramsey. In the first game, The Last of Us (2013), Joel Miller is tasked with escorting a 14-year-old Ellie across a post-apocalyptic United States in an attempt to create a cure for an infection to which Ellie is immune. While players briefly assume control of Ellie, the artificial intelligence primarily controls her actions. Ellie reappeared as the playable character in the downloadable content prequel The Last of Us: Left Behind, in which she spends time with her friend Riley. In The Last of Us Part II (2020), players control a 19-year-old Ellie as she seeks revenge on Abby.
