Pietro Simone Agostini, also Piersimone Agostini, (* about 1635 in Forlì; † October 1, 1680 in Parma) was an Italian composer.
Piersimone Agostini was banished from his hometown because of his involvement in a murder case. He then embarked on a military career during which he took part in the war for Crete against the Turks and was appointed Knight of the Order of the Golden Spur for his merits.
He studied music under Giovanni Battista Mazzaferrata († 1681) in Ferrara.
Agostini had his first success as a composer in Genoa where he composed two operas
which were performed at the ''Teatro Falcone'' He composed two additional operas for the ''Teatro Ducale'' in Milan.
He was banished from Genoa for immoral behavior and moved to Rome.
After successful opera performances in Rome, Prince Giovanni Battista Pamphili (1648-1709) appointed him to the position of Music Director at the Church of Sant'Agnese in Agone.
Due to a lack of opera commissions, Agostino left Rome and from September 1697 he found
a position as Kapellmeister at the court of the Duke of Parma, Ranuccio II Farnese.
Almost at the same time he took over the position of Kapellmeister from Simpliciano Olivo (1594-1680) at the ducal basilica of Santa Maria della Steccata. Agostini died suddenly only one year later.
Agostini composed a total of eight stage works, some of which have been lost.
Among his best works are the approximately 30 secular cantatas which are comparable to those of Alessandro Stradella.
