Georgina Sparks is a fictional character in the Gossip Girl novel series and a recurring character on the television series of the same name, in which she was portrayed by Michelle Trachtenberg.

While the novel series portrays her as a harmless, friendly drug-addicted little girl, the television adaptation portrays her as a cruel, manipulative young socialite who creates havoc throughout the show. Originally conceived as the series' primary antagonist, by the final season Georgina came into the good graces of the Upper East Side - even becoming a member of their inner circle.

She is notable for her manipulative machinations and sudden returns throughout the series, and for appearing in all the finales, and most recently the latter half of the fifth season in light of cast members Taylor Momsen and Jessica Szohr departing. In the sixth season of the show, she appears in eight of ten episodes. Georgina also appears in the second season of the HBO Max sequel series.

Georgina Spark (Sparks in the television series), known as Georgie, is a pretty New York celebutante and probably the wealthiest character in the saga. She somewhat resembles Snow White: she is slim and has long, straight, silky dark brown hair, almost black, thin black eyebrows, dark brown eyes, dark red lips, pale skin and an average-sized bust. She is a talented equestrian who has won numerous awards. A rumor has it that she studied at the same boarding school — Hanover Academy — as Serena. Georgie is fatherless and her mother largely neglects her. Lost and adrift, she has an addictive personality and often behaves in extravagant and reckless ways. Among other things, she sold her favorite competition horse to buy fifty grams of cocaine. She lost all her friends because of her troubles. She and Nate meet during a stay in rehab at the Rupture Breakaway. They date for a while and, one evening, when Nate comes to see her at her mansion, the young woman overdoses after taking an excessive amount of various pills. The golden boy then saves her life by contacting their addiction counselor. They later go together to Sun Valley for spring break, where Georgie runs into Serena and Blair Waldorf. Georgie’s relationship with Nate ends when she and Chuck Bass are arrested by the police for sledding completely naked on a public highway. She then returns to rehab, this time in Switzerland.

In sixth grade, she and Chuck lost their virginity together.

She gave Chuck a South American snow monkey as a thank-you to his parents for getting them both out of jail and then covering up the incident. Contrary to what is shown in the television series, Georgina gets along fairly well with Serena and Chuck. Her mother and Misty Bass are cousins, which even makes her and Chuck third cousins[11]. A notable difference between her character in the book and in the television series is that, in the novels, Georgina has no cruel intentions toward anyone and interacts only minimally with the main characters. She gets along quite well with Serena and Chuck, although they do not spend much time together.

Tim Stack of Entertainment Weekly reported that Michelle Trachtenberg took on the role that actress Mischa Barton had been previously offered. The Buffy alumna was cast into the role of Georgina Sparks, described by Michael Ausiello as "an adolescent Cruella". Creator Josh Schwartz states that, "Georgina was [Serena's] enabler, her best friend, and her id." The actress stated that the character is "basically the evil bitch from hell" and that "She's been part of the Gossip kids' lives for a long time, and she's coming back around to make her presence known." She describes the role as "the best character I have ever played," saying "It's awesome playing the bad girl," and compared her previous role on Buffy as something very different from her current role as Georgina. She has stated that the character is "incredibly evil, manipulative and pretty much just takes no prisoners, and she doesn't care about the consequences." Trachtenberg also draws her on her "own painful teen experience in her L.A. private school," citing her work on Harriet the Spy as an inspiration for her portrayal of the character.

Georgina Sparks, a girl who had frequently partied with Serena van der Woodsen, returns to New York from Switzerland. Georgina is first mentioned in "The Blair Bitch Project" when Serena discovers that she had been sending her packages of champagne, porn, sex toys and drugs—not Chuck. Serena apologizes to Chuck and shows him Georgina's recent letter. However, he later reassures her that Georgina is still in Switzerland.
