Catherine Gatsby is a secondary character in The Great Gatsby, the sister of Tom Buchanan’s mistress Myrtle Wilson. She is portrayed as a lively, unfiltered figure who moves between working-class Queens and the glitzy parties of Manhattan, with no direct stake in the wealthy characters’ personal dramas.

Catherine is portrayed as lively, unfiltered, and unconcerned with the social niceties that govern the behavior of wealthy characters. She does not feel pressure to lie to protect the reputations of people with more money or social status than her, making her observations unusually honest for the novel’s social context. Jot down one specific trait you notice in her first scene to reference in your next quiz.
As a character with no ties to East or West Egg’s wealthy circles, Catherine acts as a neutral observer of conflicts that other characters are too invested in to report honestly. She confirms that Tom and Myrtle’s affair is an open secret among working-class communities, which undercuts Tom’s attempts to present himself as a loyal husband to Daisy. Use this insight to answer class discussion questions about narrative reliability in the novel.
Catherine’s treatment after Myrtle’s death highlights the sharp class divide that defines the novel. She has firsthand knowledge of Tom’s relationship with Myrtle, but her testimony is dismissed by authorities and ignored by the wealthy characters who control the narrative of Myrtle’s death. Map one example of her treatment to the novel’s broader critique of class inequality for your next essay draft.
Catherine’s casual acceptance of Tom and Myrtle’s affair reveals that moral apathy is not limited to the wealthy upper class of the novel. She sees no problem with the affair, and does not attempt to intervene or inform Daisy, even when Tom and Myrtle’s fights turn violent. Note this parallel between working-class and upper-class values to add depth to your thematic analysis.
Catherine contrasts sharply with Daisy Buchanan and Jordan Baker, who are both constrained by the expectations of upper-class 1920s society. Daisy feels trapped in her marriage, and Jordan lies to maintain her social reputation, while Catherine faces no such pressure to conform to social norms. Write a 1-sentence comparison between Catherine and one other female character to use in your next discussion.
Minor characters like Catherine are often used in essay prompts to test your understanding of the novel’s broader thematic structure, rather than just plot recall. Framing Catherine as a narrative device that exposes unspoken truths about class and morality will help you stand out from other students who only focus on main characters.

No, Catherine shares the last name Gatsby by coincidence; she is Myrtle Wilson’s sister and has no direct personal connection to Jay Gatsby for most of the novel.
Catherine appears in two key scenes: the Manhattan apartment party where Tom and Myrtle host Nick, and the aftermath of Myrtle’s death, where she gives testimony to authorities about the accident.
Catherine’s outsider perspective lets Fitzgerald reveal information to the reader that main characters like Nick or Tom would never admit openly, making her a key tool for exploring themes of class and narrative reliability.
The novel does not follow Catherine after she gives testimony about Myrtle’s death, as her narrative purpose is fulfilled once she reveals what she knows about Tom and Myrtle’s relationship.
