Fleetwood Mac in Chicago is an album by the rock band Fleetwood Mac released on 5 December 1969. It was the result of a recording session in early 1969 at Chess Records in Chicago (home to Muddy Waters, Howlin' Wolf, et al.) with Fleetwood Mac, then a young British blues band, and a number of famous Chicago blues artists from whom they drew inspiration. The album has also been released, with slightly different track listings, under the titles Blues Jam at Chess and Blues Jam in Chicago Volumes One and Two.
