Trey Lorenz (born January 19, 1969 in Florence, South Carolina) is an American singer and songwriter.

Lorenz began his career supporting singer Mariah Carey on her first promotional tour in 1990, and the following year he provided background vocals on her album Emotions.

Lorenz again served as Carey's backing singer on her 1992 appearance on the television show MTV Unplugged, where he and Carey sang a cover of the Jackson 5's "I'll Be There" (1970).

Their performance was released as a single that went to number one in the United States.
Lorenz was subsequently offered a record deal and recorded a critically successful self-titled debut album.

The single "Someone to Hold" (co-written and co-produced by Carey, who also sang backup vocals) peaked at number nineteen on the U.S. Billboard Hot 100 singles chart.

Lorenz's second album, Mr. Mista, was released on September 16, 2006. Among the songs on the new album is "See You Sometime", a song Lorenz sang during the Charmbracelet World Tour.

Lorenz launched his second album during the time he was prominently featured in Carey's 2006 The Adventures of Mimi Tour, doing background vocals and singing three songs: "Never Too Much", "A House Is Not a Home" and "Crazy", during one of her many costume changes.
