El Corrido de Rosita Alvírez is a Mexican ballad. It tells the story of young Rosita Alvírez who, despite her mother's warnings, decides to go to a baile (dance) one night. She gets there and a man named Hipolito asks her to dance. She declines, and Hipolito shoots her three times because of the embarrassment he feels. In the end, Rosita is in el cielo (heaven) and Hipolito is in la cárcel (jail).
