Claude Debussy's Préludes are two sets of pieces for solo piano. They are divided into two separate livres, or books, of twelves preludes each. Unlike previous cycles of twenty-four preludes, like that of Chopin, Debussy's does not follow a set pattern of key signatures, but instead moves arbitrarily through the possible keys, not even touching five of them. The first book was written between December of 1909 and February of 1910, and the second between 1911 and April of 1913.

Debussy never intended the pieces to be performed in a series; he thought of them as individual works. The titles were given by the composer to create images or sensory associations for the listener. Several are poetically vague. For example, the meaning of Voiles the title of the second preludes of the first book, is ambiguous, since the noun's gender is unknown. They are written at the end of the music, suggesting that the pieces are in fact preludes for thoughts.
The most famous of the preludes are both from the first book: La fille aux cheveux de lin is a brief but harmonically complex Pre-Raphaelite expression of beauty. La cathédrale engloutie alludes to the legend of the sunken city of Ys. Only the spires of the cathedral were visible above the waves of the Atlantic.
