Led Zeppelin's Autumn 1969 North American Tour was the fourth concert tour of North America by the English rock band. The tour commenced on 17 October and concluded on 8 November 1969. This tour is notable for the fact that Led Zeppelin were the first rock act to perform at the prestigious Carnegie Hall in New York City since the Rolling Stones in the mid-1960s, and also for their three performances at Bill Graham's Winterland Ballroom in San Francisco (the alternate venue offered to those bands which pulled crowds too large for the smaller Fillmore West venue).
