An English rock band formed in London in 1967 by former Yardbirds guitarist Jeff Beck. Their innovative approach to heavy-sounding blues and rhythm and blues was a major influence on popular music.

The first Jeff Beck Group included guitarist Beck, vocalist Rod Stewart, rhythm guitarist Ronnie Wood, with bass players and drummers changing regularly, before settling on Aynsley Dunbar and switching Wood to bass. This line up spent most of 1967 playing the UK club circuit. During this time, they released 3 singles in Europe and 2 in the USA, the first, Hi Ho Silver Lining, being the most successful. Frustrated that the band was not playing a strict enough blues set for his taste, Dunbar left and was replaced by Micky Waller, a bandmate of Stewart's from Steampacket. Waller went on to play with the band all through 1968 and early 1969, and was their longest-lasting drummer.

Peter Grant, a road manager at the time, booked a short US tour, during which they played well-received 4 shows at the Fillmore East as second on the bill to the Grateful Dead. By the time they wrapped up the tour at San Francisco's Fillmore West, Grant had secured them a new album contract with Epic Records.

After several more albums and US tours, all of which were reasonably well-received, in-fighting within the band plus Stewart's developing solo career resulted in Beck breaking up the band on the eve of the Woodstock Music Festival, at which they had been scheduled to perform, a decision he later stated that he regretted.

A second Jeff Beck Group was formed in 1970, but had limited success and was disbanded in 1972.
