Ivanhoe is a historical novel by Sir Walter Scott, first published in 1820 in three volumes and subtitled A Romance. Ivanhoe, set in 12th century England, has been credited for increasing interest in romance and medievalism; John Henry Newman claimed Scott "had first turned men's minds in the direction of the Middle Ages", while Carlyle and Ruskin made similar assertions of Scott's overwhelming influence over the revival, based primarily on the publication of this novel.

Ivanhoé is an 1826 pastiche opera in three acts with music by Gioachino Rossini to a French-language libretto by Émile Deschamps and Gabriel-Gustave de Wailly, after Walter Scott's novel of the same name. The music was adapted, with the composer's permission, by the music-publisher Antonio Pacini from Rossini's operas, namely Semiramide, La Cenerentola, La gazza ladra, and Tancredi in order to introduce his music to Paris. An examination of the score shows that Pacini also used music from Bianca e Faliero, Armida, Maometto II, Aureliano in Palmira, Sigismondo, Torvaldo e Dorliska, Mosè in Egitto and an amount of newly composed music including fanfares and the gallop that was later to become famous from its inclusion in Guglielmo Tell. The work was premiered on 15 September 1826, at the Odéon Theatre.
