"Come on Over Baby (All I Want Is You)" is a song co-written by American pop singer Christina Aguilera, Paul Rein, Johan Aberg, Celebrity Status (C. Blackmon, R. Cham, E. Dawkins), Guy Roche, Shelly Peiken and Ron Fair for Aguilera's self-titled debut album Christina Aguilera (1999). It was co-produced by Fair and Celebrity Status.

The song is about Aguilera eying a prospective boyfriend and declaring come on over baby ... 'cause all I want is you. It was released as the album's fourth and final single on September 26, 2000 and it was the first single on which Aguilera had been given significant creative control. It peaked at number one in the U.S., and was very successful in other countries as well.

The brand new look, which included more revealing outfits and streaks of red and blue in her hair, was also used for her debut Spanish language album Mi Reflejo and also for her first headlining tour in Summer 2000.
