Wesley is a UK-based guitar brand founded by John Wesley and operated through Wesley Guitars Ltd, based in Barnard Castle, County Durham, England. The brand built its reputation in the budget-friendly segment of the electric guitar market, offering imported instruments that were often set up personally by John Wesley before shipping. Over its run, the company sold an estimated 25,000 guitars, basses, mandolins, and banjos worldwide, with earlier Korean-made models (pre-2005) generally regarded more highly than later Chinese production. Collectors distinguish between a pre-2005 and post-2005 logo design to help date instruments.

Wesley's catalog covered a wide range of familiar body styles, including Stratocaster- and Telecaster-style solidbodies, Les Paul-style singlecuts, semi-acoustic hollowbodies, and more specialized shapes like Flying V and Mockingbird copies. Signature models from the line include the Wesley Vermont and the Wesley Doppler. The brand also produced acrylic/perspex guitars and a range of basses, including violin-style and P-style variants. Typical retail prices sat in the £50–£150 range, and owner reviews frequently highlight the instruments' playability and build quality relative to their low cost.

New Wesley models are no longer in regular production, and John Wesley has shifted focus toward guitar repair and restoration work, occasionally offering NOS and reconditioned Wesley instruments alongside other marques through the Wesley Guitars shop.

Wesley has 7 products cataloged on Equipboard, including Solid Body Electric Guitars, Electric Basses, and Banjos. Their gear is featured by 1 artist, with the strongest followings in Electronic and Rock. Notable users include Mark Andrews.
