Les Barricades Mystérieuses (The Mysterious Barricades) is a piece of music that François Couperin composed for harpsichord in 1717. It is the fifth piece in his "Ordre 6ème de clavecin" in B-flat major, from his second book of collected harpsichord pieces (Pièces de Clavecin). It is emblematic of the style brisé characteristic of French Baroque keyboard music.
