Jangle or jingle-jangle is a sound typically characterized by undistorted, treble-heavy electric guitars (particularly 12-strings) played in a droning chordal style (by strumming or arpeggiating). The sound is mainly associated with pop music as well as 1960s guitar bands, folk rock, and 1980s indie music. It is sometimes classed as its own subgenre, jangle pop. Music critics use the term to suggest guitar pop that evokes a bright mood.

Despite forerunners such as Jackie DeShannon, the Searchers and the Everly Brothers, it was the Beatles and the Byrds who are commonly credited with launching the popularity of jangle. The name derives from the lyric "in the jingle-jangle morning, I'll come following you" from the Byrds' 1965 rendition of Bob Dylan's "Mr. Tambourine Man". Although many subsequent jangle bands drew significantly from the Byrds, they were not necessarily folk rock as the Byrds were.

Since the 1960s, jangle has crossed numerous genres, including power pop, psychedelia, new wave, post-punk, and lo-fi. In the 1980s, the most prominent bands of early indie rock were jangle pop groups such as R.E.M. and the Smiths.
