Giulio Regondi (born 1822 in either Geneva or Lyon; died May 6, 1872 in London) was an Italian classical guitarist, concertinist and composer.
Regondi was a child prodigy. Fernando Sor dedicated his Souvenir d'amitié, op. 46 to Regondi in 1831, when the boy was just nine.
Most of Regondi's music was written for the concertina, though his guitar music is probably better known. His works for solo guitar comprise a set of etudes and five larger works.
