Eastar is a beginner-focused musical instrument brand operating as a sub-brand of Donner Music, with a U.S. office in Charlotte, North Carolina. The company designs and sells affordable starter instruments aimed at students and primary-to-intermediate players, typically packaged as complete kits that bundle the instrument with accessories like cases, mouthpieces, cleaning supplies, rosin, and shoulder rests so a new player has everything needed to start.

Its catalog spans several instrument families: brass (Bb trumpets such as the ETR-380 and ETR-380B, pocket trumpets, and trombones), woodwinds (clarinets, alto and soprano saxophones, recorders, piccolos, and flutes), strings (violin sets in standard sizes including the EVA-2), percussion (drum kits, snare drums, and bongos), and keyboards (digital and portable pianos). Products are widely distributed through Amazon, Walmart, and Donner's own e-commerce sites in addition to the brand's own storefront.

Eastar's positioning is squarely on the value end of the market rather than the professional tier, and it is most often discussed by music teachers, school band programs, and parents shopping for a first instrument. It is generally not associated with signature artist models or pro-level endorsements.

Eastar has 2 products cataloged on Equipboard, including Harmonicas and Recorders.
