The Bob Dylan World Tour 1966 was a concert tour undertaken by the American musician Bob Dylan, from February to May 1966. Dylan's 1966 World Tour was notable as the first tour where Dylan employed an electric band backing him, following him "going electric" at the 1965 Newport Folk Festival. The musicians Dylan employed as his backing band were known as the Hawks, who later became famous as the Band.

By 1965, Bob Dylan was the leading songwriter of the American folk music revival. The response to his albums The Freewheelin' Bob Dylan and The Times They Are a-Changin' led the media to label him the "spokesman of a generation".
