Twelve Little Preludes (French: Douze petits Préludes; German: ), BWV 924–930, 939–942 and 999, is a 19th-century compilation of short pieces, collected from various 18th-century manuscripts written by Johann Sebastian Bach and others. Notwithstanding their diverse origin and characteristics, they were published as a set of twelve keyboard preludes by Bach in, amongst others, the 36th volume of the Bach-Gesellschaft Ausgabe (BGA).
