Rodelinda, regina de' Longobardi (HWV 19) is an opera seria in three acts composed for the first Royal Academy of Music by George Frideric Handel. The libretto is by Nicola Francesco Haym, and was based on an earlier libretto by Antonio Salvi set by Giacomo Antonio Perti in 1710. Salvi's libretto originated with Pierre Corneille's play Pertharite, roi des Lombards (1653), based on the history of Perctarit, king of the Lombards in the 7th century.
Rodelinda was first performed at the King's Theatre in the Haymarket, London, on 13 February 1725. It was produced with the same singers as Tamerlano. There were 14 performances; it was repeated on 18 December 1725, and again on 4 May 1731. In 1735 and 1736 it was also performed in Hamburg at the Oper am Gänsemarkt. The first modern production - in heavily altered form - was in Göttingen on 26 June 1920 where it was the first of a series of modern Handel opera revivals produced by the Handel enthusiast Oskar Hagen.
