Rockapella is an American a cappella musical group formed in 1986 in New York City. Their name is a portmanteau of "rock" and "a cappella". The band sings original vocal music and a cappella covers of pop and rock songs; over time, their sound has evolved from high-energy pop and world music toward a more R&B-style sound. Rockapella originally found their biggest success in Japan, while in North America, they are best remembered for their role on the hit PBS Kids game show Where in the World Is Carmen Sandiego? as a vocal house band and resident comedy troupe, as well as the singers of the show's main theme song.

The band has released 18 albums, both in North America and overseas, and 3 compilation albums in Japan. The text "All sounds provided by the voices and appendages of Rockapella", the central idea of the band, has appeared on all of their CDs since the addition of their vocal percussionist.
