The Missa Gaudeamus is a musical setting of the Ordinary of the Mass by Franco-Flemish composer Josquin des Prez, probably composed in the early or middle 1480s, and published in 1502. It is based on the gregorian introit Gaudeamus Omnes and its setting is for four voices. The number of sources for this work is relatively high: two printed editions, four reprints and seven manuscripts.
