Domenico Mazzocchi (1592 – 21 January 1665, aged 72) was an Italian Baroque composer of the generation after Claudio Monteverdi. He was a composer of only vocal music, motets, oratorios and madrigals which have continuo, similar to the late Monteverdi.
He is associated with providing music for the popes, particularly Cardinal Maffeo Barberini, later Pope Urban VIII.
His younger brother Virgilio Mazzocchi was also a Roman composer who had a similar career as a Vatican music provider.
