A tribute act, tribute band, tribute group or tribute artist is a music group, singer, or musician who specifically plays the music of a well-known music act. Tribute acts include individual performers who mimic the songs and style of an artist, such as Elvis impersonators covering the works of Elvis Presley or groups like The Iron Maidens, an all-female band that pays tribute to Iron Maiden.

An Elvis impersonator is an entertainer who impersonates or copies the look and sound of American musician and singer Elvis Presley. Professional Elvis impersonators, commonly known as Elvis tribute artists (ETAs), work all over the world as entertainers, and such tribute acts remain in great demand due to the unique iconic status of Elvis. In addition, there are several radio stations that exclusively feature Elvis impersonator material. Some of these impersonators go to Graceland on the anniversary of Presley's death to make their personal tribute to the artist.
