Teseo ("Theseus", HWV 9; ) is an opera seria with music by George Frideric Handel, the only Handel opera that is in five acts. The Italian-language libretto was by Nicola Francesco Haym, after Philippe Quinault's Thésée. It was Handel's third London opera, intended to follow the success of Rinaldo after the unpopular Il pastor fido.
