Euphoria is an American teen drama television series created and principally written by Sam Levinson for HBO and based on the Israeli miniseries of the same name created by Ron Leshem and Daphna Levin. The main character is Rue Bennett (Zendaya), a troubled teenage drug addict who struggles to get sober and find her place in the world. Though Rue is the central focus, the series provides backstories for the rest of the main cast at the beginning of most episodes.

Euphoria's executive producers include Levinson, Zendaya, Ron Leshem, and Gary Lennon. The series is filmed at Ulysses S. Grant High School in Los Angeles, California, Sony Pictures Studios in Culver City, California, and Warner Bros. Studios in Burbank, California. Outside California, it is filmed at Warner Bros. Studios in Leavesden, Hertfordshire, and in Dublin, London, New York City, Rome, and Singapore. The series has received generally positive reviews, with praise for its cinematography, score, performances of the cast, and approach to its mature subject matter. It has also been a subject of controversy for its nudity and sexual content, which critics found excessive due to the teenage setting. It is the fourth most-watched series in HBO history, behind Game of Thrones, The Last of Us, and House of the Dragon.

Season one of Euphoria premiered on June 16, 2019. Two one-hour specials were broadcast in December 2020 and January 2021. The second season premiered on January 9, 2022. In February 2022, the series was renewed for a third season. The series has received numerous accolades, including a nomination for the Primetime Emmy Award for Outstanding Drama Series. For her performance, Zendaya has won two Primetime Emmy Awards, a Critics' Choice Television Award, and a Golden Globe Award for Best Actress. Sweeney, Domingo, and Martha Kelly have also received Emmy nominations for their acting, with Domingo winning Outstanding Guest Actor in a Drama Series.
