Gossip Girl is an American teen drama television series based on the novel series of the same name written by Cecily von Ziegesar. The series, developed for television by Josh Schwartz and Stephanie Savage, ran on The CW network for six seasons from September 19, 2007, to December 17, 2012.

Narrated by the unknown, omniscient blogger "Gossip Girl" (voiced by Kristen Bell), the series revolves around the lives of privileged upper-class adolescents living in Manhattan's Upper East Side (UES). The series begins with the return of Upper East Side teenage "it girl" Serena van der Woodsen (Blake Lively) from a mysterious absence. She is reunited with her popular frenemy Blair Waldorf (Leighton Meester) and her mother Lily (Kelly Rutherford), and she also meets Dan Humphrey (Penn Badgley)—an aspiring writer from Brooklyn who is one of Serena's main love interests throughout the show. Other main characters include Nate Archibald (Chace Crawford), Chuck Bass (Ed Westwick), Jenny Humphrey (Taylor Momsen), Vanessa Abrams (Jessica Szohr), Rufus Humphrey (Matthew Settle) and Ivy Dickens (Kaylee DeFer).

The success of Gossip Girl led to many adaptations outside the United States. The show received numerous award nominations and won 18 Teen Choice Awards. The CW officially renewed Gossip Girl for a sixth and final season on May 11, 2012. The final season, consisting of 10 episodes, premiered on October 8, 2012, and ended on December 17, 2012.
