OQAN is a Spanish musical instrument and audio equipment brand created by Adagio Group, a Spain-based distributor of musical instruments and pro audio gear that operates across Spain, Portugal, Italy, and France. The name is drawn from okan, a Yoruba word meaning "soul," and the brand positions itself around accessible pricing for players at home, in rehearsal rooms, in studios, and on stage. All OQAN products carry a 3-year warranty.

The catalog spans several categories rather than a single specialty: acoustic, classical, and electric guitars (including the Riff Series of Telecaster- and Les Paul-style electrics, with models such as the QGE-RTC2 and QGE-LP10), basses, ukuleles, digital keyboards and pianos, percussion (cajons and hand percussion), orchestral and wind instruments such as violins and saxophones, PA and audio equipment, and accessories. Acoustic and classical lines include entry-level instruments like the QGC-15 and QGA-16, often sold as starter packs.

OQAN is generally found in the budget and beginner-to-intermediate tier of the European market, distributed through Spanish and Portuguese music retailers and online via Amazon Spain and platforms like Reverb. The brand's identity, developed by Barcelona agency CATandCAT (later This is Umami), uses a black base palette with neon accent colors that vary by product family.

OQAN has 3 products cataloged on Equipboard, including Beginner Kits, Steel-string Acoustic Guitars, and Ukuleles.
