Orlando is an opera seria in three acts by George Frideric Handel written for the King's Theatre in London in 1733. The Italian libretto was adapted from Carlo Sigismondo Capece's L'Orlando after Ludovico Ariosto's Orlando Furioso, which was also the source of Handel's operas Alcina and Ariodante. More an artistic than a popular success at its first performances, Orlando is today recognised as a masterpiece.

Roland was a Frankish military leader under Charlemagne who became one of the principal figures in the literary cycle known as the Matter of France. The historical Roland was military governor of the Breton March, responsible for defending Francia's frontier against the Bretons. His only historical attestation is in Einhard's Vita Karoli Magni, which notes he was part of the Frankish rearguard killed in retribution by the Basques in Iberia at the Battle of Roncevaux Pass.
