Silla (full title Lucio Cornelio Silla, HWV 10) is an opera seria (referred to as a dramma per musica) in three acts by George Frideric Handel. The Italian-language libretto was by Giacomo Rossi. The story concerns the Roman dictator Lucius Cornelius Sulla (138–78 BC) as recounted by Plutarch.
The opera appears to have been a pièce d'occasion, which may have been performed only once. The music was recycled in Handel's later opera Amadigi di Gaula.
