Peerless Guitars is a South Korean guitar manufacturer founded in 1970 and based in Busan, with production at its factory in Gimhae. The company began as an OEM builder, producing instruments for a roster of well-known brands that has included Gretsch, Epiphone, and Alvarez, at one point turning out tens of thousands of guitars a month. Over time, Peerless scaled back its contract work to concentrate on a smaller catalog of instruments sold under its own name.

The brand is best known for archtop and semi-hollow electrics aimed at jazz and blues players, along with a line of steel-string acoustics. Model families include the Monarch, Imperial, Martin Taylor signature, Gigmaster, and Retromatic archtops, the Wizard semi-hollow, and acoustic series such as the New 70, New 75, and Elegance. Guitars are built using traditional carved-top methods with solid tonewoods, and the company positions itself on craftsmanship rather than volume.

Peerless has a following among jazz archtop enthusiasts and has produced a signature model for guitarist Martin Taylor. The brand is distributed internationally through specialist dealers and maintains a reputation in the archtop community for delivering hand-built quality at a lower price point than comparable American and Japanese luthier-built instruments.

Peerless has 10 products cataloged on Equipboard, including Semi-Hollowbody Electric Guitars and Acoustic-Electric Guitars. Their gear is featured by 4 artists, with the strongest followings in Rock, Blues, and Pop. Notable users include Amy Shark, Martin Taylor, and William Farquarson.
