Giulio Cesare in Egitto (pronounced [ˈdʒuːljo ˈtʃeːzare in eˈdʒitto]; Italian for "Julius Caesar in Egypt", HWV 17), commonly known as Giulio Cesare, is a dramma per musica (opera seria) in three acts composed for the Royal Academy of Music by George Frideric Handel in 1724. The libretto was written by Nicola Francesco Haym who used an earlier libretto by Giacomo Francesco Bussani, which had been set to music by Antonio Sartorio (1676). The opera was a success at its first performances, was frequently revived by Handel in his subsequent opera seasons and is now one of the most often performed Baroque operas.
