Superstrat is a name for an electric guitar design that resembles a Fender Stratocaster but with differences that clearly distinguish it from a standard Stratocaster, usually to cater to a different playing style. Differences typically include more pointed, aggressive-looking body and neck shapes with increased cutaways to facilitate access to the higher frets, an increased number of frets on the fingerboard, a contoured heel at the neck joint facilitating easier higher fret access, the usage of humbucking pickups, and locking vibrato systems, most commonly the Floyd Rose.

The Fender Stratocaster, colloquially known as the Strat, is a model of electric guitar designed between 1952 and 1954 by Leo Fender, Bill Carson, George Fullerton, and Freddie Tavares. The Fender Musical Instruments Corporation has continuously manufactured the Stratocaster since 1954. It is a double-cutaway guitar, with an extended top "horn" shape for balance. "Stratocaster" and "Strat" are trademark terms belonging to Fender. Guitars that duplicate the Stratocaster by other manufacturers are sometimes called S-Type or ST-type guitars. Many prominent rock musicians have been associated with the Stratocaster for use in studio recording and live performances, most notably Eric Clapton, Buddy Holly, David Gilmour, Mark Knopfler, Jimi Hendrix, Stevie Ray Vaughan, Mark Speer and George Harrison.
