Angelo Berardi (c. 1636 in Sant'Agata Feltria – 9 April 1694 in Rome) was an Italian music theorist and composer.
Berardi was born in Sant'Agata Feltria. He received early education at Forlì under Giovanni Vincenzo Sarti (1600–1655). From 1662 he was maestro di cappella in Montefiascone, in the province of Viterbo, Lazio. He studied under Marco Scacchi at Gallese at some time between 1650 and Scacchi's death in 1662; he included two motets by Scacchi in Book 1 of his Documenti armonici of 1687, and also cites him frequently. By 1667, when his Salmi vespertini concertati, Op. 4, were published, Berardi was maestro di cappella at the cathedral in Viterbo. He was organist and maestro di cappella at Tivoli from 21 September 1673 to 1679, and maestro di cappella and "professor of music" at the cathedral in Spoleto in 1681 or from 1679–1683. He was a canon at the collegiata of S. Angelo, Viterbo, when the Documenti armonici (1687) and Miscellanea musicale (1689) were published.
By 17 August 1692 he was maestro di cappella at Santa Maria in Trastevere in Rome.
