Ace in the Hole Band is the backup band for American country music performer George Strait, who was the band's lead singer before beginning his solo career in the early 1980s. The band formed at San Marcos, Texas in the 1970s, and recorded several singles for "D Records" including the Strait-penned "I Just Can't Go On Dying Like This" and "I Don't Want To Talk It Over Anymore". After Strait attained status as the "King of Country", the group released an album of its own in 1995 featuring vocals from Darrell McCall and Mel Tillis.

A backup band or backing band is a musical ensemble that typically accompanies a single artist who is the featured performer. The situation may be a live performance or in a recording session, and the group may or may not have its own name, such as "The Heartbreakers", or "Bob Wills and his Texas Playboys" in the 1930s. Often, backup bands contain sidemen who are skilled but not known to the public; these musicians may be replaced or substituted at any time without noticeable impact on the performance.
