Di Giorgio is a Brazilian guitar manufacturer founded in 1908 in São Paulo by Italian immigrant Romeu Di Giorgio, who initially built violins, mandolins, and violas before the workshop evolved into a factory specializing in classical and acoustic guitars. The company has remained a family business passed from father to son, with the factory now located in Franco da Rocha in the state of São Paulo.

The brand is closely tied to the history of Brazilian popular music, particularly bossa nova. Under the leadership of Reinaldo Di Giorgio in the 1960s, Di Giorgio became the preferred supplier of high-end nylon-string guitars for a generation of Brazilian composers and performers. The Autor 3 model, in particular, became associated with bossa nova pioneers including João Gilberto and Baden Powell, and the brand has been linked to artists such as Tom Jobim, Roberto Carlos, Marcos Valle, and Dorival Caymmi.

Di Giorgio's catalog centers on classical, acoustic, and electroacoustic guitars suited to MPB, bossa nova, samba, and classical repertoire. The lineup includes the Série Artistica (including the Autor 3), the Tárrega, Talent, student-oriented models like the Estudante 18, and cutaway electroacoustic classicals such as the 38E, alongside steel-string folk and dreadnought models.

Di Giorgio has 7 products cataloged on Equipboard, including Classical & Nylon-String Guitars. Their gear is featured by 2 artists, with the strongest followings in Jazz, Latin, and Folk, World, & Country. Notable users include João Gilberto and Antônio Carlos Jobim.
