Spear Guitars is a guitar brand associated with South Korean origins, with production of its instruments taking place primarily in Indonesia, and some models built in China or Vietnam. The company produces a full range of fretted instruments, including electric guitars, bass guitars, and acoustic guitars, and positions itself in the affordable-to-mid-range market with a stated focus on offering higher-end features without a high-end price.

The lineup has included the Gladius SP, a neck-through rock guitar, the RD-Relic with P90 pickups, and the Evil Monkey Series, alongside more traditional shapes such as the Thorn Series Stratocaster-style models, the Tomcat, the S-100 SG-style single cutaway, and the Flextool bass. Instruments ship with a mix of proprietary Spear Monster humbuckers and third-party pickups including EMG-HZ and Seymour Duncan models, depending on the guitar.

Distribution has historically been handled through regional partners rather than a single global storefront, with Black i Distribution handling the UK market and a separate Spear Guitar USA presence covering North America. The brand has a modest following among budget-conscious players and is discussed on guitar forums such as Ultimate Guitar, SevenString.org, and Harmony Central, where it is generally compared to other import brands in the same price tier.

Spear Guitar has 7 products cataloged on Equipboard, including Solid Body Electric Guitars.
