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.

Many tribute bands, in addition to playing the music of an artist or group, also try to emulate the vocal styles and overall appearance of that group, to make as close an approximation as possible. Others introduce a twist on the original act; for example, Dread Zeppelin plays Led Zeppelin songs in a reggae style with a lead singer dressed up as Elvis Presley, while Gabba perform the songs of ABBA in the style of the Ramones. Tribute bands usually name themselves based on the original band's name (sometimes with a pun), or on one of their songs or albums.
