Johannes Cesaris (fl. 1406 – 1417) was a French composer of the late Medieval era and early Renaissance. He was one of the composers of the transitional style between the two epochs, and was active at the Burgundian court in the early 15th century. One of his pieces, the ballade Le dieus d'amours, was copied into the famous Chantilly Codex, the illuminated manuscript which is the primary source for the Avignon repertory of the ars subtilior.
