La Nativité du Seigneur is an organ cycle by French composer Olivier Messiaen, completed in 1935. The work, conceived as nine meditations on the Nativity, showcases Messiaen's early mature techniques—modal harmony and modes of limited transposition, non-retrogradable rhythms, and vivid organ registration informed by Gregorian chant and birdsong—producing a contemplative, colouristic and rhythmically innovative liturgical sound-world and marking a formative consolidation of techniques he would later expand.
