Led Zeppelin's Autumn 1969 European Tour was a concert tour of Europe by the English rock band, commencing on 3 October and concluding on 12 October 1969. The tour consisted of four concerts held on the European mainland, but also included a single performance at the Lyceum Ballroom in London, England. This brief tour was organised to promote the imminent release of the band's second album, Led Zeppelin II. The album was released in late October 1969, just following the conclusion of this tour.
