The Fender Jaguar is an electric guitar by Fender Musical Instruments characterized by an offset-waist body, a relatively unusual switching system with two separate circuits for lead and rhythm, and a short-scale 24" neck. Owing some roots to the Jazzmaster, it was introduced in 1962 as Fender's feature-laden top-of-the-line model, designed to lure players from Gibson. During its initial 13-year production run, the Jaguar did not sell as well as the less expensive Stratocaster and Telecaster, and achieved its most noticeable popularity in the surf music scene. After the Jaguar was taken out of production in 1975, vintage Jaguars became popular first with American punk rock players, and then more so during the alternative rock, shoegazing and indie rock movements of the 1980s and 1990s. Fender began making a version in Japan in the mid-1980s, and then introduced a USA-made reissue in 1999. Since then, Fender has made a variety of Jaguars in America, Mexico, Indonesia and China under both the Fender and Squier labels. Original vintage Jaguars sell for many times their original price.

Both the Fender company and vintage guitar authorities date the introduction of the Jaguar to 1962. One writer states that the model was introduced in December 1960, but a 1962 ad featuring a Jaguar automobile in the background referred to the "new" Fender Jaguar.

1960s advertising for the Jaguar often had beach themes, underscoring the guitar's appeal to surf musicians. Photographs for the campaign, done by Bob Perine, included photographs of bikini-clad girls on sandy beaches holding Jaguars—many of these featured Perine's daughter and her friends. The guitar was not, however, heavily publicized by surf players themselves, although The Beach Boys' Carl Wilson is featured in one early publicity photo.

The Jaguar never enjoyed the popularity of its Stratocaster and Telecaster siblings. After several upgrades—which included custom finishes, a bound neck, pearloid block inlays, maple fingerboard with black binding, and block inlays—the Jaguar was discontinued in December 1975 after a thirteen-year production run.

Punk and early new wave guitarists such as Tom Verlaine of the band Television (who can be seen playing a Jaguar on a 2003 album cover) adopted the Jaguar for both contrarian and economic reasons; its lack of mainstream use made it both a style statement and less expensive than guitars of comparable quality. In the 1990s the popularity of the Jaguar and Jazzmaster exploded after they were used by guitarists such as Scott Hill, John Squire, Kurt Cobain (for whom a signature model was introduced), Kevin Shields, Black Francis, J Mascis, Brian Molko, Rowland S. Howard, Thurston Moore, John Frusciante, Will Sergeant and Johnny Marr (who has a signature model). Despite this, Jaguars still fetch considerably less than Telecasters and Stratocasters of similar vintage.

One of the reasons why the Jaguar was used by indie rock artists is the sonic possibilities offered by the bridge construction. The bridge and vibrato unit of the Jaguar and the Jazzmaster help produce sympathetic resonance since there is a considerable length of string between the bridge and the tailpiece. Additionally, by strumming the strings behind the bridge, a characteristic chiming sound can be created, an effect which has been exploited by artists like Sonic Youth.

Fender reissued the 1962 version of the Jaguar in 1999 as part of its American Vintage Reissue (AVRI) Series (lower cost Japanese-made versions were available between 1984 and 2015, originally made of basswood and then alder like their American counterparts). Several other variations have been released within the last decade, including several humbucker versions and a Jaguar bass guitar in 2006. Fender Japan produced Jaguars for its own domestic market with numerous special editions including an accurate version of Kurt Cobain's modified model until Fender chose to end the licensing agreement in place since the early 1980s in favor of taking over Japanese production themselves in 2015. There are notable differences between the typical Japanese models and their American counterparts. One of the more notable examples would be the electronics: Japanese production models typically used cheaper wiring, miniature pots throughout the guitar (as opposed to only in the rhythm circuit as would be found on original and AVRI examples), lower-quality pickups, and shielding paint as opposed to brass shielding plates installed in the cavities (Japanese guitars made before 96/97 also have brass shielding) seen on typical American Jaguars. Original and AVRI variants have nitrocellulose lacquer finishes, while Japanese versions would typically be finished in polyester, though there are rare Japanese examples with nitrocellulose finishes as well. US-produced AVRI Jaguars often did not sport matching headstocks, unlike their vintage counterparts, however, many Japanese models do, and also offer some custom colors not found as easily on American models.^{[citation needed]}

In the late 2000s, Fender began to offer limited editions of the AVRI models from a few of their more-popular retailers, with these specific variants being referred to as the Thin Skin series. A collaboration between several notable American guitar retailers (Such as Dave's Guitar Shop in Wisconsin and Wildwood Guitars in Colorado) culminated in the release of otherwise typical AVRI Jaguars as well as Jazzmasters, Telecasters, and Stratocasters, but in more sought-after Classic finishes that Fender otherwise had little interest in releasing themselves. These were almost identical to the production AVRI models, with the exception of their finish options and the inclusion of matching headstocks, a 9.5" fretboard radius instead of the vintage-accurate 7.25", and jumbo fretwire. The Thin Skin models used 100% nitrocellulose finishes, a departure from the production models, which used polyurethane undercoats/sealers. These Thin Skin models also featured thinner color and clear coats. These models were available in a number of Custom Colors, and, unlike the standard production '62 Jaguars, these did feature matching headstocks.
