Ottone, re di Germania is an opera by George Frideric Handel, to an Italian–language libretto adapted by Nicola Francesco Haym from the libretto by Stefano Benedetto Pallavicino for Antonio Lotti's opera Teofane. It was the first new opera written for the Royal Academy of Music (1719)'s fourth season and had its first performance on 12 January 1723 at the King's Theatre, Haymarket in London. Handel had assembled a cast of operatic superstars for this season and the opera became an enormous success.
