Esperanza Cordero
The narrator and main character. She is young, observant, and angry in a quiet way. She watches the women around her get trapped and decides she will be different. Her voice carries the whole book, and her desire to leave Mango Street is the engine of the story.
Marin
An older girl who waits for a boyfriend to rescue her. She is glamorous to Esperanza but also stuck. She represents the fantasy of escape through romance, and the book shows that fantasy does not work.
Sally
A girl Esperanza's age who is beautiful and uses that beauty to get away from her abusive father. She marries young, thinking it is freedom. Her husband turns out to be controlling. Sally shows that trading one man for another is not escape.
Rafaela
A young woman whose husband locks her inside on nights he fears she will leave. She lowers a bag from her window to get things from the street below. She is one of the book's clearest images of a woman with no freedom.
Nenny
Esperanza's younger sister. She is more innocent and less troubled by Mango Street than Esperanza. She functions partly as a contrast: Esperanza carries the weight of awareness that Nenny does not yet have.
The Three Sisters
Three older women who appear at a neighborhood funeral. They tell Esperanza she will leave but must return for those left behind. They give the book its moral center, the idea that escape carries responsibility.
Esperanza's mother
A woman who is smart and capable but gave up her own dreams. She tells Esperanza she quit school because she was ashamed of her clothes. She is a warning and a source of love at the same time.
