The Missa Sine nomine is a setting of the Ordinary of the Mass by Renaissance composer Josquin des Prez. It is a work of his maturity, probably dating from the period after he returned to Condé-sur-l'Escaut in 1504. It is one of Josquin's only masses not to be based on pre-existing material, and like the Missa ad fugam, it is a canonic mass.
