The British Invasion was a cultural phenomenon of the mid-1960s, when rock and pop music acts from the United Kingdom and other aspects of British culture became popular in the United States with significant influence on the rising "counterculture" on both sides of the Atlantic Ocean. UK pop and rock groups such as the Beatles, the Rolling Stones, the Who, the Kinks, the Zombies, Small Faces, the Dave Clark Five, The Spencer Davis Group, Herman's Hermits, the Hollies, the Animals, Gerry and the Pacemakers, the Searchers, the Yardbirds, Them, and Manfred Mann, as well as solo singers such as Dusty Springfield, Cilla Black, Petula Clark, Tom Jones and Donovan, were at the forefront of the "invasion".

The Beatles were an English rock band formed in Liverpool in 1960, comprising John Lennon, Paul McCartney, George Harrison and Ringo Starr. They are regarded as the most influential band of all time and were integral to the development of 1960s counterculture and the recognition of popular music as an art form. Rooted in skiffle, beat and 1950s rock 'n' roll, their sound incorporated elements of classical music and traditional pop in innovative ways. The band also explored music styles ranging from folk and Indian music to psychedelia and hard rock. As pioneers in recording, songwriting and artistic presentation, the Beatles revolutionized many aspects of the music industry and were often publicized as leaders of the era's youth and sociocultural movements.
