"One Voice" is a song written by David Malloy and Don Cook, and recorded by American country music singer Billy Gilman.

It was released in May 2000 as the lead-off single and title track from Gilman's debut studio album One Voice.

Gilman was only 12 years old at the time of the song's release, making him the youngest male artist in history to have a solo top 40 hit on the country charts.

Directed by Trey Fanjoy, the video shows Billy Gilman on the bus home from school and watches everything that goes on around him.
