"¿Qué Creías?" ("What Did You Think?") is a song by American singer Selena, taken from her third studio album, Entre a Mi Mundo (1992). It was written by Pete Astudillo and A.B. Quintanilla following A.B.'s challenge for Astudillo to write a song before arriving in Las Vegas from California. Astudillo decided on writing a track inspired by works done by Mexican singer Juan Gabriel. A mariachi ballad, the song was described by Selena as a song that speaks for all women. It is the singer's torch song and the lyrics describe Selena's unwillingness to forgive a cheating partner; she addresses her former lover who took her for granted, telling him that she can live without him. Critics praised Selena's emotive vocal range and female style of lyricism.
