Giuseppe Giordani (December 19, 1751 - January 4, 1798) was an Italian composer, mainly of opera.
He was born in Naples, where he studied music with Domenico Cimarosa and Niccolò Antonio Zingarelli. In 1774 he was appointed as music director of the chapel of the Duomo of Naples. His first opera (L'Epponina) was released in 1779. His sacred drama La distruzione di Gerusalemme was a notable success at the Teatro San Carlo of Naples in 1787. He became maestro di cappella at the Cathedral of Fermo in 1791.
Until recently the popular aria Caro Mio Ben was ascribed to Giordani, however after recent scholarship his brother Tommaso Giordani is now attributed.
