Starsun is a Chinese guitar manufacturer founded in 1993 and based in Guangdong, China. The brand was launched by Soundkay (also referenced as Guangdong Shengkai Musical Instrument Co., Ltd. / Soundcolor Musical Instruments), which operates a large-scale factory complex producing instruments for both the domestic Chinese market and export markets in Europe, the Americas, and Southeast Asia.

The company's catalog spans acoustic guitars, classical guitars, electric guitars, and bass guitars across a wide range of price points. Their lineup includes dreadnought-style acoustics such as the MJG201CE (a cutaway acoustic-electric with onboard EQ) and the DF20C, alongside electric models built around classic single-cutaway and Explorer-style body shapes. Most offerings sit in the entry-level and intermediate tiers, aimed at students, hobbyists, and players looking for affordable instruments.

Within China, Starsun is regarded as one of the more established domestic guitar brands, with a reputation built on consistent build quality at accessible price points rather than boutique-tier construction or signature artist models. Its instruments are widely distributed through Chinese music retailers and appear on the international second-hand market through platforms such as Reverb.

Starsun has 2 products cataloged on Equipboard, including Semi-Hollowbody Electric Guitars and Solid Body Electric Guitars.
