"Debo Hacerlo" (English: "I Must Do It") is a dance song written, produced and performed by Mexican singer-songwriter Juan Gabriel. It was released as the first single from his compilation album of the same title (1987). This song became the last original song recorded by Gabriel, until 1994, due to a copyright dispute with BMG over his repertoire, and was later covered by Ana Gabriel, Nydia Rojas, Pandora, José Octavio and Aleks Syntek.

"Debo Hacerlo" became the last original song recorded by Mexican singer-songwriter Juan Gabriel, due to his refusal to record any new material, since the dispute with BMG over copyrights to his songs was unresolved. Moreover, upon listening to "Debo Hacerlo" one can hear the same intro from his previous single, "Hasta que te Conoci", and in fact, some of the chord progression from "Hasta" carries onto "Debo Hacerlo". In order to release this song, the record label selected eleven previously released tracks from Gabriel's catalog. Gabriel did a special appearance in the 'Festival Acapulco 1988' to present the song. The song became a success in México where it spent seven months within the Top 5, leading to the parent album to sell six million copies in Latin America and receiving a platinum certification in United States for sales of 100,000 units.

The song debuted on the Billboard Hot Latin Tracks chart at number 30 on December 26, 1987 and climbed to the top ten five weeks later. It reached the top position of the chart on April 16, 1988, replacing "Ay Amor" by Mexican singer-songwriter Ana Gabriel and being replaced one week later by Los Bukis' "Y Ahora Te Vas". This song became Gabriel's second number-one hit in the Hot Latin Tracks chart as a lead performer, after "Yo No Sé Qué Me Pasó" in 1986 and his fourth number-one single as a songwriter. It ended 1988 as the fifth best-performing single of the year.
