The Fender Musical Instruments Corporation, initially named the Fender Electric Instrument Manufacturing Company, was started by Leo Fender in 1946, and is one of the most widely recognised manufacturers of electric guitars, electric basses and amplifiers.

Fender is particularly important because of its role in bringing solid body electric guitars to the masses. Fender offered the first mass-produced solid-body Spanish-style electric guitar, the Telecaster (originally named the 'Broadcaster', 'Esquire' is a single pickup version); the first mass-produced electric bass, the Precision Bass (or P-Bass); and the enormously popular Stratocaster guitar (or 'Strat' for short). While other companies and luthiers had produced electric guitars since the late 1920s, nearly all were either hollow-body guitars with pickups attached, or more specialized instruments such as Rickenbacker's solid-body Hawaiian lap steel guitars.

Other popular and/or notable Fender instruments include the Mustang, Jazzmaster, Jaguar, Starcaster, Duosonic, and Bronco guitars; basses such as the Jazz Bass, the 'Telecaster Bass' reissue of the original 1950s Precision Bass; a line of lap steels; three models of electric violin, and the Fender Rhodes electric piano.

Its headquarters are in Scottsdale, Arizona, with manufacturing facilities in Corona, California, and manufacturing facilities in Ensenada (Mexico), Korea and Japan.
