Michael Kelly Guitars is an American musical instrument company founded in 1999 by Tracy Hoeft and based in Clearwater, Florida. The company designs guitars, basses, and mandolins that are built to its specifications overseas, primarily in South Korea, and distributes them worldwide. Its catalog spans acoustic guitars, electric guitars, acoustic-electric hybrids, acoustic and electric mandolins, and basses, with an emphasis on distinctive features such as port-construction acoustic bodies and modified pickup configurations on its electric models.

The brand is perhaps best known for the Dragonfly acoustic bass line, offered in 4-string, 5-string, and fretless variants, which helped establish its presence among bassists. Its electric lineup includes the Patriot single-cut series and the Triple 50 line, while the Mod Shop range pairs the company's body and neck designs with aftermarket pickups from makers such as Seymour Duncan, Lindy Fralin, and Bare Knuckle. The Dragonfly bass in particular has been associated with players including Duff McKagan of Guns N' Roses and Shavo Odadjian of System of a Down.

Michael Kelly has 55 products cataloged on Equipboard, including Solid Body Electric Guitars, Acoustic & Acoustic-Electric Basses, and Semi-Hollowbody Electric Guitars. Their gear is featured by 11 artists, with the strongest followings in Rock, Electronic, and Pop. Notable users include Hunter Agufish, Les Claypool, and Robert Trujillo. Most Michael Kelly products fall in the mid-tier range — professional-grade without flagship pricing.
