La Calliroe is an opera in three acts by Josef Mysliveček set to a libretto by Matteo Verazi that is based on Greek legends about the Oceanid Callirrhoe. This opera (and all the rest of Mysliveček's operas) belong to the serious type in Italian language referred to as opera seria. Vocal pieces from the opera composed for the singer Luigi Marchesi in the role of Tarsile were widely copied in eighteenth-century collections of operatic arias.
