Booker T. and the MG's were an American instrumental R&B/funk band that was influential in shaping the sound of Southern soul and Memphis soul.

The original members of the group were Booker T. Jones (organ, piano), Steve Cropper (guitar), Lewie Steinberg (bass), and Al Jackson Jr. (drums).

In the 1960s, as members of the Mar-Keys, the rotating slate of musicians that served as the house band of Stax Records, they played on hundreds of recordings by artists including Wilson Pickett, Otis Redding, Bill Withers, Sam & Dave, Carla Thomas, Rufus Thomas, Johnnie Taylor and Albert King.

They also released instrumental records under their own name, including the 1962 hit single "Green Onions."

In 1965, Steinberg was replaced by Donald "Duck" Dunn, who played with the group until his death in 2012.

The band was inducted into the Rock and Roll Hall of Fame in 1992, the Musicians Hall of Fame and Museum in Nashville, Tennessee in 2008, the Memphis Music Hall of Fame in 2012, and the Blues Hall of Fame in 2019.
