The Great Fantasia and Fugue in G minor, BWV 542, is an organ prelude and fugue by Johann Sebastian Bach. It acquired that name to distinguish it from the earlier Little Fugue in G minor, which is shorter. This piece is not to be confused with the Prelude and Fugue in A minor, which is also for organ and also sometimes called "the Great".
