Giovanni Guicciardi (12 January 1819 – 4 October 1883) was an Italian opera singer who sang leading baritone roles in the opera houses of Italy and Portugal.
He is most remembered today for having created the role of Count di Luna in Verdi's Il trovatore, although he created several other leading roles in operas by lesser known Italian composers.
He accumulated a considerable fortune during the course of his career.
After his retirement from the stage, he taught without payment in music schools in his native city, Reggio Emilia, and presided over a charity for orphaned musicians.
