The Fender Esquire was a solid-body electric guitar manufactured by the Fender Musical Instruments Corporation of Los Angeles. It was the first solid-bodied guitar marketed by the company, and made its debut in 1950.

A solid-body musical instrument is a string instrument such as a guitar, bass or violin built without its normal sound box and relying on an electromagnetic pickup system to directly detect the vibrations of the strings; these instruments are usually plugged into an instrument amplifier and loudspeaker to be heard. Solid-body instruments are preferred in situations where acoustic feedback may otherwise be a problem and are inherently both less expensive to build and more rugged than acoustic electric instruments.
