Paolo Agostino, or Agostini (Augustinus in Latin) (1593-1629) was an Italian musician, who was born at Valerano. He studied under G. B. Nanini, according to the dedication in the third and fourth books of his masses. Subsequently he became the son-in-law of his master.
He succeeded Ugolini as conductor of the pope's orchestra in St Peter's. His musical compositions are numerous and of great merit, an Agnus Dei for eight voices being specially admired.
