"Waiting for Tonight" is a song written by Maria Christensen, Michael Garvin, and Phil Temple.
The song was originally recorded by Christensen's girl group 3rd Party for their debut studio album, Alive (1997).
Two years after the group disbanded, American singer Jennifer Lopez recorded her own version of the song for her debut studio album, On the 6 (1999).
A Spanish version of the song, entitled "Una Noche Más", was adapted by Manny Benito and also recorded for the album.
"Waiting for Tonight" was released on October 27, 1999, by the Work Group, as the third single from On the 6.
