Hohner Musikinstrumente GmbH & Co. KG is a German manufacturer of musical instruments, founded in 1857 by Matthias Hohner (1833–1902). The roots of the Hohner firm are in Trossingen, Baden-Württemberg. Since its foundation, and though known for its harmonicas, Hohner has manufactured a wide range of instruments, such as kazoos, accordions, recorder flutes, melodicas, banjos, electric, acoustic, resonator and classical guitars, basses, mandolins and ukuleles (under the brand name Lanikai).

From the 1940s through 1990s, the company also manufactured various electric/electronic keyboards. Especially in the 1960s and 1990s, they manufactured a range of innovative and popular electromechanical keyboard instruments; the cembalet, pianet, basset, guitaret, and clavinet. In the 1980s, several Casio synthesizers (such as the Casio HT-3000/Hohner KS61midi and the VZ-1/HS-2) were sold under the Hohner brand.

Nowadays, Hohner produces harmonicas, melodicas, accordions and recorder flutes.
