RJ Guitars is a boutique electric guitar brand based in the Philippines, founded by Ramon "RJ" Jacinto — a Filipino musician known as "Mr. Guitarman of the Philippines" who has performed since the late 1950s, including collaborations with The Ventures. The company has been manufacturing guitars in the Philippines since the late 1980s, and its Philippine facility and craftsmen were trained in partnership with Japan's Deviser/Aska, the parent organization behind Japanese brands such as Momose, Bacchus, Headway, and Seventy Seven, as well as James Tyler Japan.

The lineup centers on handbuilt, vintage-inspired bolt-on electrics at prices below typical boutique tiers. Product lines include the RJ Custom Shop, the Supervintage series, the Skycaster, and more accessible GigLine and Basic Electrics models. The company also makes its own hand-wound Custom Shop pickups. RJ Guitars was the first Philippine guitar brand to exhibit at NAMM and has expanded internationally, selling globally through its online store and retail partners.

RJ Guitars has 7 products cataloged on Equipboard, including Steel-string Acoustic Guitars, Solid Body Electric Guitars, and Acoustic-Electric Guitars.
