Blonde on Blonde is American singer-songwriter Bob Dylan's seventh studio album, released in May or June 1966 on Columbia Records and produced by Bob Johnston. Recording sessions commenced in New York in October 1965, with numerous backing musicians, including members of Dylan's live backing band, The Hawks. They continued until January 1966, but yielded only one track that made it onto the final album—"One of Us Must Know (Sooner or Later)". At Johnston's suggestion, Dylan, accompanied by keyboard player Al Kooper and guitarist Robbie Robertson, moved to the CBS studios in Nashville, Tennessee. These sessions, augmented by some of Nashville's top session musicians, were more fruitful, and in February and March all the remaining songs for the album were recorded.

The album completed the trilogy of rock albums that Dylan recorded in 1965 and 1966, commencing with Bringing It All Back Home and Highway 61 Revisited. Blonde on Blonde is often ranked by critics as one of the greatest albums of all time. Combining the expertise of Nashville session musicians with a modernist literary sensibility, the album's songs have been described as operating on a grand scale musically, while featuring lyrics one critic called "a unique blend of the visionary and the colloquial". It was one of the first double albums in rock music.
