Aaron Hall (born 10 August 1964, The Bronx, New York) is an American R&B singer and songwriter. He was a member of the 1980s and 1990s trio Guy, along with new jack swing founder Teddy Riley and songwriter Timmy Gatling, and later Hall's brother Damion Hall.

As member of Guy, Hall rose to fame as lead singer on hits like «Groove Me», «I Like» and «Piece of My Love» (from the group's self‑titled debut album) and «Let's Chill» and «Do Me Right» (from their second album, The Future) before the trio disbanded in the end of 1991. His vocal distinction is similar to that of Charlie Wilson, a member of the R&B/funk group, The Gap Band. They also collaborated in 1992 on the soundtrack to Eddie Murphy's hit film, Boomerang.

As a solo singer, his hits include the #1 R&B single, «Don't Be Afraid» (from the Juice soundtrack in 1991 and also on the popular videogame Grand Theft Auto: San Andreas, playing on New Jack Swing radio station CSR 103.9) and his Top 3 single, «I Miss You» (from his solo debut in 1993), reaching #2 on the R&B chart and later peaking at #14 on the Billboard Hot 100, becoming his biggest pop hit. He also participated in several projects with R. Kelly and joined Kelly and a group of fellow R&B singers in the song «U Will Know» from the Jason's Lyric soundtrack. Hall also recorded a duet with Jamaican reggae vocalist Patra, on her album Scent Of Attraction in 1995. The single they recorded was of the same name. He has a son with Gloria Velez. He was featured with K‑Ci & JoJo and Danny Boy in the 2Pac single «Toss It Up» in his 1996 album The Don Killuminati: The 7 Day Theory using the pseudonym Makaveli.

Hall reunited with his brother and Riley as Guy on their 1999 reunion album, Guy III, which featured the modest hit, «Dancin'».

In July 2005, Aaron Hall released his most recent album entitled Adults Only: The Final Album.
