Dillion is a guitar company founded in 1996 by John Vinci (who performs as John Dillion) and based in Cary, North Carolina. Before launching the brand, Vinci worked in sales and product roles for Dean, B.C. Rich, and Guild, and the company was built around the idea of offering mid-priced instruments inspired by classic American designs. Dillion guitars are manufactured in Korea and imported through Dillion USA, with headstocks marked "Made for Dillion USA" to distinguish them from an unaffiliated Canadian company using a similar name.

The catalog consists largely of recreations and variations of vintage-style instruments. Electric models cover Stratocaster, Telecaster, Les Paul, SG, PRS, and Firebird-style solid bodies in both 25.5" and 24.75" scale lengths, along with semi-hollow options. The brand also produces dreadnought and folk-sized acoustics, Telecaster- and Rickenbacker-style basses in 4- and 5-string configurations, lap steels, and custom mandolins. Notable model names in the line include the Big G and the Rockinbetter DRG series.

Dillion sits in the affordable import segment, often discussed on forums like The Gear Page and the Telecaster Discussion Page as a budget alternative to the vintage instruments it emulates. The company maintains a roster of endorsing artists drawn from blues, rock, and metal scenes.

Dillion has 11 products cataloged on Equipboard, including Solid Body Electric Guitars, Acoustic-Electric Guitars, and Acoustic & Acoustic-Electric Basses. Their gear is featured by 4 artists, with the strongest followings in Rock, Pop, and Folk, World, & Country. Notable users include Glen Campbell, Ryan Peake, and Shawn Milke.
