Risa Musical Instruments is a German ukulele maker founded in 2001 and based in Groß-Umstadt, Germany. The company is best known for its distinctive electric ukuleles, including the stick-shaped Uke-Solid, the Uke'Ellie, and guitar-bodied models like the LP-style and T-style tenor electric ukuleles that borrow design cues from classic electric guitars.

Risa's lineup spans soprano, concert, tenor, baritone, guitarlele, bass, and banjolele instruments, with construction typically built around mahogany or maple bodies and fitted with humbuckers or single-coil pickups on the electric models. The Uke-Solid, which can be equipped with steel strings, has become the company's best-selling instrument and is often cited as one of the few purpose-built electric ukuleles aimed at rock, funk, and metal players.

Alongside manufacturing, Risa operates a large European ukulele retail and wholesale business, handles repairs, and offers custom builds out of its Groß-Umstadt workshop.
