The Bootleg Series Vol. 4: Bob Dylan Live 1966, The "Royal Albert Hall" Concert

Live 1966: The "Royal Albert Hall" Concert is a two-disc live album by Bob Dylan, released in 1998. It is the second installment in the ongoing Bob Dylan Bootleg Series on Legacy Recordings, and has been certified a gold record by the RIAA. It was recorded at the Manchester Free Trade Hall during Dylan's 1966 world tour, though early bootlegs attributed the recording to the Royal Albert Hall so it became known as the Royal Albert Hall Concert. Extensively bootlegged for decades, it is an important document in the development of popular music during the 1960s.

The set list consisted of two parts, with the first half of the concert being Dylan alone on stage performing an entirely acoustic set of songs, while the second half of the concert has Dylan playing an "electric" set of songs alongside his band the Hawks. The first half of the concert was greeted warmly by the audience, while the second half was highly criticized, with heckling going on before and after each song from those who objected to Dylan's use of a full rock and roll band.
