Gary Allan Herzberg (born December 5, 1967), known professionally as Gary Allan, is an American country music artist.

Signed to Decca Records in 1996, Allan made his country music debut with the release of his single "Her Man", the lead-off to his gold-certified debut album Used Heart for Sale, which was released in 1996 on Decca. His second album, It Would Be You, followed in 1998. Allan's third album, Smoke Rings in the Dark, was his first one for MCA Nashville (to which he has been signed ever since) and his first platinum album. His next albums, Alright Guy (2001) and See If I Care (2003), both were also certified platinum while Tough All Over (2005) and Greatest Hits (2007) were both certified gold. His seventh studio album, Living Hard, was released later in 2007.
