 Main characters
 Serena van der Woodsen
Portrayed by Blake Lively since the pilot and one of the few characters to appear in every episode, Serena Celia van der Woodsen is the it girl of the Upper East Side and best friend of Blair Waldorf. Recently returning from a Connecticut boarding school for reasons unknown to her friends, as was her departure from Manhattan a year prior to the show's beginning. Serena van der Woodsen comes across as down-to-earth for someone from the UES, but things, relationships (Dan, Nate) and opportunities (fashion shoots) seemed to be handed to her on a silver platter. Serena's past as the partying and promiscuous 'it girl' causes her to leave Manhattan for mysterious reasons. What's even more strange is that she abruptly returns to the high society world of Manhattan. During the first season, she deals with a spiteful Blair, her incident with Nate and a new relationship with Dan. Her relationship with Dan first faces the return of his best friend, Vanessa's and her gradual warming up to her, and Dan's acceptance of Serena and the high society world she lives in. Their relationship ends during her mother's wedding to Bart Bass due to her frenemy Georgina making life horrible for her and her friends. The second season has Dan and Serena renewing their relationship, but facing the reality that they could never be together, Dan's incident with a new girl and a scandal with a teacher, their residual feelings for each other and the discovery of their parents' love child. This season also sees Serena's mother, Lily, adopting Chuck Bass, thus making the two of them step-siblings. Serena leaves Manhattan during the summer and returns in the third season a local celebrity. She was with Nate, but decided to breakup with him. Serena went to Paris with her best friend Blair, trying to figure out if she wants to be with Nate or Dan. When she got back, they both were with other people. Serena decides to go to Columbia. As a freshman in Columbia, she constantly had to deal with many situations; a classmate named Juliet Sharp, plotting a lot of devious schemes to ruin her life with many reasons involving her family, her mother's secret forged signature on an affidavit sending her English professor to prison for 3 years so that Serena can admit back into Constance with cleared clean records, her younger brother, Eric, feeling lonely and depressed again, her estranged cousin, Charlie, who is a con named Ivy, hired by Carol Rhodes herself to scam out Lily's checks for money while Ivy "Charlie" started to fall for Dan, then went terribly suicidal from not taking her daily medication. In season 5, Serena starts to have feelings for Dan once again, but everything turns into chaos when she sees Dan and Blair kiss in Valentine's Day. Not only does it ruin her dreams of being again with Dan, but also her friendship with Blair. She became Gossip Girl in the "Con Heir" episode after receiving the mysterious package which contains the laptop where Georgina wrote a note. The note contains the password to Gossip Girl's website and e-mail address where all the tips are sent. Toward the end of the episode though, someone who claims that she is the real Gossip Girl sent her a message and told her that she wants the password so the she can have her site back. During the beginning of the episode "It Girl, Interrupted" she messaged GG and said she will return but she will do something first. After a fight with Blair that ends their friendship, Serena has sex with Dan at the Shepard's divorce party and records it as a way to get back at Blair, but gets caught by Dan, who ends his friendship with Serena also. Serena is last seen on a train doing cocaine with a guy. In season 6, after being missing for the entire summer, her friends search for her, thinking the worst. They soon find her okay and in a happy relationship under the alias: Sabrina. She also wants nothing to do with her friends, as she is in a good place. After the truth about her life is revealed, Steven and Serena go back to New York, where Serena has to deal Steven's seventeen-year-old daughter and Nate's new girlfriend, Sage, who sabotages her relationship with Steven. Dan befriends Serena, in order to get a story out of it. He then falls for her once again and they later kiss, which makes them an official couple once again. Later in the season, Dan launches a terrible story about Serena, which causes them to break up and for Serena to leave as Dan slips another story about Serena into her bag which turns out to be another version of the story but all of the great things about her. She confronts him and asks which story is the "real him" and demands answers and a recap on their history. It is then revealed that Dan and Serena first met at an Upper East Side party at Blair's house, which they had talked for a bit, but Serena was drunk. He then decided to try to get to know her, but he knew that he could never enter the world that she lives in unless he writes himself into it. It is finally then revealed that Dan Humphrey is Gossip Girl. Serena is at first upset but then finds it funny, after realizing that it all makes sense. She also realizes that without Gossip Girl, she would've never realized that the people in her life are all family, if she had left. In the end of the finale, it skips ahead 5 years and reveals that Serena and Dan get married.
 Blair Waldorf
Portrayed by Leighton Meester since the pilot and like Serena, one of the few characters to appear in every episode, Blair Cornelia Waldorf is the queen bee of the social scene of Manhattan and Constance Billard High School. An only child, she is introduced as the daughter of a divorced fashion designer mother and a homosexual father and the longtime girlfriend of Nate Archibald, although she also fell for and is dating Nate's best friend Chuck Bass. Blair is often portrayed as naughty, shallow, intelligent, and scheming. Despite her uptight, frivolous nature, she "works for everything she's ever gotten", in contrast to Serena, and despite her snobbish ways, she is a good friend and constantly looks out for those she cares about. Blair faces her crumbling relationship with Nate and a new, secret relationship with Chuck in the first season and her return to power as Queen Bee after a power struggle with Jenny Humphrey. Chuck leaves her alone over the summer, leading to a short relationship with a British noble during the second season. Her relationship with Chuck changes as he tries to win her back and she tries to own up to her own feelings towards him. Blair gets tired of the high school pettiness until her admission to Yale is compromised. The loss of Yale destabilizes her life plan, and she resumes her relationship with Nate in the hope of getting back on track, only to realize that he was meant to be her "high school boyfriend". By the end of the second season, Blair and Chuck embark on a relationship, continuing on into season three and dissolving into chaos at its end. Season four sees Blair trying to juggle her feelings for Chuck, her aspirations to be a successful woman and the opportunities offered her by Prince Louis, whose love will mean she has to give up on Chuck. At the end of the season, Chuck chooses to let her go, believing that he is incapable of making her happy, and she accepts Louis' proposal of marriage. In season five, Blair finds out that she is pregnant with Louis' baby, which produces conflicting feelings as she starts to find herself drawn to Chuck again. After a heartfelt apology from Chuck, the two are ready to run away and start a new life together, before they are badly injured in a car crash. Blair loses her baby and almost loses Chuck; as a result, she makes a promise to God to keep her vows to Louis and never be with Chuck again, as long as Chuck's life is spared. Blair then gets married with Louis, only to discover that he is furious with her for publicly declaring her love for Chuck on their wedding day, and intends for their marriage to be a sham. While attempting to extricate herself from her marriage, she seeks the help of Dan who, as she later discovers, has a crush on her. Chuck makes minor schemes and attempts to steer Blair away from Dan but is unsuccessful, and eventually steps aside, secretly paying Blair's dowry so she's free to be with whomever she chooses. Dan and Blair face a number of obstacles throughout the course of their short relationship, including sexual incompatibility, difficulty assimilating into each other's lives, and trust issues, especially once Blair starts to spend time with Chuck again. When Dan tells Blair he loves her, she is unable to respond in kind, and then her diary entry is leaked to Gossip Girl, exposing to the world that she still loves Chuck. Dan tells her she has to choose between them, and she debates the merits of the "safety" she feels with Dan, and her love for Chuck, who has "devastated her, but also made her the happiest she's ever been." Ultimately she chooses Chuck, only to discover that he is too hurt and angry by how she has treated him to take her back. Season 5 ends with Blair saying that she's "all in" and vowing to fight for Chuck. Throughout season 6, Blair and Chuck decide that it is better if they accomplish the goals that they have set for themselves before they get together as a couple. As Chuck finds information on his father and goes out to destroy him, Blair tries to find a good job for her which is managing her mother's job at Waldorf Designs. Blair waits for Chuck while becoming the new head of Waldorf Designs and tells Chuck that she has been waiting too long and helps find information on Chuck's father. In the episode before the finale, Bart dies by falling off a building rooftop with Chuck refusing to save his life. In the season 6 finale, Chuck and Blair attempt to go in hiding from the cops because they (the cops) want to ask questions about his fathers' death and says that he may be involved. In the end of the episode, Chuck and Blair get married so that when the cops ask if there were any witnesses (which Blair was), she can deny that Chuck was involved with his fathers' death due to the terms of marriage that she would be unable to go against her husband. Chuck and Blair get away happily with no evidence that Chuck had anything to do with his fathers' case and skips ahead 5 years to show that Chuck and Blair have a child.

Before Bart Bass, she was divorced from Dr. William van der Woodsen. Despite her constant concern for appearances and status in high society, it can be assumed that she lived as indulgently as Serena during her wild child years. Her similarity to Serena can especially be seen when she cries and is unable to make any decisions, both of which are behaviors commonly seen in Serena. It is revealed she was also institutionalized at 19 much like her son Eric. It was later revealed that it was not because of a suicide attempt, but because she was pregnant with Rufus's child.

 Gossip Girl
Voiced by Kristen Bell, "Gossip Girl" is the narrator of the show, an unseen character whose gossip commentary blog is widely visited by the youths of the Upper East Side social scene, often stirring the lives of the main characters. Her identity remains a secret but still manages to lure readers with catty wordplay and scandalous news provided via tips through the members of the Upper East Side social network. Gossip Girl has avoided discovery twice: first, when her blog was the subject of getting shut down during Dan's incident with Miss Carr; and second, when Serena attempted to confront her personally in the second season episode, "The Graduates," by texting her and saying she knows Gossip Girl's identity. However, this second attempt ultimately failed, as Gossip Girl invited the entire class with her, masking her identity. Gossip Girl then gave everyone the perfect present: A clean slate and that she will be following them to college. Gossip Girl showed a personality trait in the fourth season episode, "The Townie", where she responded to a request from Blair for the location of Juliet with the address and "find the bitch," showing that she does not appreciate anyone who may threaten the validity of her blog, leading one to believe she may be personally motivated. In the fifth season episode, "G.G.", it shows Georgina Sparks behind the computer posting a message as Gossip Girl, but in the following episode she reveals to her husband/accomplice that the real "Gossip Girl" abandoned her post following Chuck and Blair's accident. Serena becoms "Gossip Girl 3.0" in the season five episode, "Con Heir", after Georgina ("Gossip Girl 2.0") sends the power laptop and the blog's password to her. The real Gossip Girl steals back her post with the power laptop in episode 22, "Raiders of the Lost Ark," with the help of Nate and Lola. In the series finale, Sage advises Nate to find out who Gossip Girl really is after seeing his old research of Gossip Girl. Nate had to give up his research as a part of the deal for information from Gossip Girl herself. With everything resolved, Nate is now determined to find out who Gossip Girl is by going through his research again. Dan had been releasing chapters of his second book to multiple blogs, each containing stories specific to one person, with disastrous events. The final chapter of the book was given to Nate from Dan, who uses it to propel The New York Spectator forward in the ratings. Everybody gets a message from The Spectator, revealing Dan as Gossip Girl all along. His true motivation behind Gossip Girl was his love for Serena and the need to get in the elitist world of Manhattan, which Dan couldn't get because he wasn't born into that world. One moment, years in the past, Dan accidentally got in a birthday party of someone, he met Serena for the first time and fell in love with her. After that, Serena disappeared and Dan vowed himself that one day he would be a force to reckon with. So he made the identity of Gossip Girl himself, and posted the first post about Serena in the ninth grade. Just soon after Gossip Girl was established, he got the tips and e-mails from everyone in New York. When Serena returned from boarding school, Gossip Girl becomes really famous by sending the news to everyone that Serena was back in town. Everyone comments that Gossip Girl was not at fault but everyone else for providing Gossip Girl with the information. With Dan revealing his identity to the world, Dan declares that Gossip Girl is officially dead. In the flashforward, we are shown a new generation of kids as Gossip Girl narrates: "You may be rid of Dan Humphrey, but you'll never be rid of me. There's always someone on the outside, wanting to get in. Who am I now? That's a secret I'll never tell. XOXO, Gossip Girl.", revealing that five years later someone else is Gossip Girl, and that the legacy goes on.
