Rockapella is an American a cappella musical group formed in 1986 in New York City. The group's name is a portmanteau of "rock" and "a cappella". Rockapella sings original vocal music and a cappella versions of other songs. Over time, their sound has evolved from high-energy pop and world music style toward a sound more influenced by R&B. Rockapella found their enduring success in Japan early in their career. They are most successful for their role as a house band and comedy troupe on the PBS children's geography game show Where in the World Is Carmen Sandiego?.

In addition to three compilation albums in Japan, Rockapella has released 19 albums in the US and Japan. Since the band's vocal percussionist was hired, the line "All sounds provided by the voices and appendages of Rockapella" has been printed on each of their CDs.
