Cheap Trick is an American rock band formed in Rockford, Illinois, in 1973. The band's work bridged elements of 1960s guitar pop, 1970s hard rock, and the emerging punk rock sound, and helped set the template for subsequent power pop artists.

Cheap Trick released its self-titled debut album in 1977. Later that year, the band found success in Japan with the release of its second album, In Color. In 1979, the band released the triple-platinum live album At Budokan and a Top 10 single, a live recording of "I Want You to Want Me". The band followed with its most commercially successful studio album, Dream Police (1979), which reached No. 6 on the Billboard 200 chart. After experiencing declining popularity in the 1980s, Cheap Trick enjoyed a major resurgence toward the end of the decade, topping the US charts with the power ballad "The Flame" (from 1988's Lap of Luxury). The band's other hits include "Surrender" (1978), "Dream Police" (1979), "Voices" (1979), "She's Tight" (1982), "Tonight It's You" (1985), a cover version of Elvis Presley's "Don't Be Cruel" (1988), "Ghost Town" (1988), and "Can't Stop Fallin' into Love" (1990).

Cheap Trick has continued releasing new music into the 21st century. The band has performed live more than 5,000 times since its formation and has sold more than 20 million albums. The band's influence has been cited by a diverse range of rock artists. Cheap Trick was inducted into the Rock and Roll Hall of Fame in 2016.
