"Si Una Vez" (English: "If Once") is a song by Mexican-American Tejano pop singer Selena, released as the fifth single from her album Amor Prohibido (1994). It was written and produced by Pete Astudillo, A.B. Quintanilla III and Bebu Silvetti. The song had first been intended for Astudillo`s debut album, but was later given to Selena to record, and released in the United States for Tejano and rhythmic contemporary stations. With progressive cumbia (Colombian music) and experimental music that incorporates both Mariachi and Rancheras, the single quickly climbed to number four on Billboard `s Latin Regional Mexican Airplay chart.
