The Les Paul Junior was originally introduced in 1954 as a single-cutaway model, with its double-cutaway counterpart arriving to the market in early 1958.
Color schemes most commonly placed on Juniors were vintage sunburst, cherry red, and TV yellow.
In 2012, two rare black models with tortoiseshell pickguard, from 1959 and 1960, were described in Vintage Guitar; the possibility was offered that black models were special-ordered for a specific store, or that the black finish was used to cover up blemishes in the wood.
In 1961, the body style of the Junior was shifted, and after conflict between Gibson and Les Paul, these models were later renamed the "SG Junior".

The Les Paul Junior is still offered today in several different variations.
Gibson offers U.S.-made Les Paul Juniors which has been given modern touches including a more slim-tapered neck.
These particular Juniors have been seen in several different incarnations since the mid-1980s in both single- and double-cutaway. (
see #Timeline) The Gibson Custom shop has also offered a period-correct Junior over the years through both its Historic and VOS branches.
These models feature the more notorious large neck or "baseball bat" neck as it is often referred to among players.

Several artists have had Juniors produced in the Gibson product line including John Lennon, Mick Jones, Peter Frampton, and often included is the Bob Marley Les Paul Special.
The Lennon model is unique for the single-coil, hexagon-shaped "Charlie Christian" pickup at the neck, a modification Lennon himself accepted when he had his actual Junior serviced in the 1970s, upon acquiring the guitar (the pickup name derives from the pickup installed on Christian's Gibson ES-150 guitar).
Green Day's Billie Joe Armstrong and Gibson have released two signature Les Paul Juniors, the first is in three custom colors including Vintage Sunburst, Classic White, and Ebony, and is based on the actual '54-'57 Juniors.
It also has some modern features requested by Armstrong, which include a slim tapered neck, as well as a specially designed "H-90" pickup which is said to be hum-canceling and it is overwound to handle more distortion.
Armstrong's second signature model is a double-cutaway in TV Yellow which also includes an "H-90" pickup.
 However, according to Armstrong's guitar tech, he does not use the H-90 in his guitars.
 He uses a Seymour Duncan Antiquity P-90 pickup.

The Les Paul Special has a similar body shape, but is equipped with two P-90 pickups and Gibson's standard four-knob, three-way switch electronics.

Ace Frehley and Gibson created a unique model of this guitar: The Gibson Les Paul Jr. Lighter.
It is a variation of a Les Paul Jr. with a DiMarzio Superdistortion pickup added by Ace.
It contained light bulbs incorporated into sequences that turned on as a marquee, but at first there were so many lamps that gave off so much energy and heat which affected Ace, that they decided to reduce them.
They installed 20 cells for rechargeable batteries "C", circuits and new lamps.

Leslie West declined an offer to have a signature model of the instrument produced because he did not want a signature guitar based on an already-existing instrument even though the Les Paul Junior was his main instrument during his heyday in Mountain.

In 2015, Gibson announced the re-release of the Gibson Les Paul Junior into their 2015 USA range.
They decided to release a newer version of the Gibson Les Paul Junior in 2018 with vintage specifications including a '50 neck profile.
