Arminio is an opera composed by George Frideric Handel. The libretto is based on a libretto of the same name by Antonio Salvi, which had been set to music by Alessandro Scarlatti. It is a fictionalisation of events surrounding the Germanic leader Arminius, who defeated the Romans under Publius Quinctilius Varus at the Battle of the Teutoburg Forest in AD 9, and his wife Thusnelda. The opera was performed for the first time at the Covent Garden Theatre on 12 January 1737.

Gioacchino Conti, best known as Gizziello or Egizziello, was an Italian soprano castrato opera singer.
