Farnace is an opera by Italian composer Antonio Vivaldi, set to a libretto by Antonio Maria Lucchini initially set by Leonardo Vinci during 1724. Vivaldi's setting received its first performance in 1727 at the Teatro Sant'Angelo in Venice. Popular at the time, and revived with great success at the Sporck theater in Prague in 1730, Vivaldi's Farnace (RV 711) slipped into oblivion until the last quarter of the 20th century when it emerged from obscurity.

Farnace was recomposed by Francesco Corselli (1705–1778) (an Italian composer with a French father).[1] Corselli's Farnace received its debut in Madrid at the Royal Theater of the Buen Retiro in 1739. Additional settings continued to be composed as late as the 1780s. One later setting is the one composed by Josef Mysliveček for the Teatro di San Carlo in Naples in 1767. It is mainly the Vivaldi setting that continues to attract interest today.
