Nuno Guitars is the signature guitar brand of Portuguese-American rock guitarist Nuno Bettencourt, best known as the lead guitarist of Extreme. Launched after the end of Bettencourt's 35-year partnership with Washburn, the company offers a tiered lineup built through partnerships with various luthiers and workshops rather than a single factory.

The catalog is organized into four series. The Thoroughbred Series consists of masterbuilt electrics hand-crafted by a luthier in Cincinnati, Ohio, with the Dark Horse as a flagship model. The Stable Series is built in Oxnard, California, and the more accessible Colt Series — which includes the N4, a design rooted in Bettencourt's longstanding N4 platform — is produced through an international manufacturing partner. An Acoustic Series, including the Lusitano AS, rounds out the line.

The brand positions itself around Bettencourt's own design input and specs, with models aimed at players looking for the ergonomics and feel associated with his playing style. Its debut releases include the Dark Horse and White Stallion electrics.
