R.W. Jameson, also marketed as Jameson Guitars and the R.W. Jameson Guitar Company, is a family-run musical instrument brand based in Highland Park, Illinois. The company focuses on entry-level and budget-friendly stringed instruments aimed at beginners and casual players, distributed primarily through Amazon, Reverb, and Guitar Center rather than traditional dealer networks.

Its catalog spans thinline acoustic-electric guitars, dreadnought acoustics, electric guitars, six-string banjo guitars, mandolins, ukuleles, and small solid-state amplifiers. The Full Size Thinline Acoustic Electric (often referenced as the 900 series) is the brand's most widely reviewed model, featuring a spruce top, basswood body, single cutaway, and an onboard four-band EQ pickup system, and is frequently recommended in beginner buying guides as a low-cost option for players who want both an acoustic and amplified sound from a single instrument.

R.W. Jameson has 6 products cataloged on Equipboard, including Banjos, Acoustic & Acoustic-Electric Basses, and Solid Body Electric Guitars.
