Navigator is a high-end electric guitar and bass line produced by ESP (Electric Sound Products) of Japan. Established alongside ESP's founding in the mid-1970s, Navigator was conceived as a series of meticulously hand-built recreations of classic American instruments — Les Paul, SG, Explorer, Flying V, Stratocaster, Telecaster, Jazz Bass and Precision Bass shapes — built exclusively in Japan at ESP's Custom Shop workshops in Tokyo.

The series is known for traditional construction methods rather than mass production: hand-selected woods, one- or two-piece bookmatched bodies, nitrocellulose lacquer finishes, vintage-correct fretwire and proportions, and premium pickups such as Seymour Duncan Antiquity and Seth Lover humbuckers fitted as stock. Common model designations include the N-LP (Les Paul style), N-ST (Stratocaster style), N-TE (Telecaster style), and the N-JB and N-PB basses, with each instrument typically built by a single luthier who selects materials based on their individual character.

Distributed primarily within the Japanese domestic market, Navigator instruments have built a cult following among collectors and players seeking high-end Japanese-made interpretations of vintage American designs. The brand sits at the top of ESP's hierarchy of traditional-style guitars, above the company's Edwards and Grassroots lines.

Navigator has 5 products cataloged on Equipboard, including Solid Body Electric Guitars. Their gear is featured by 6 artists, with the strongest followings in Rock, Metal, and Electronic. Notable users include Sugizo, Uruha, and Leda.
