Cesare Negri (c. 1535 – c. 1605) was an Italian dancer and choreographer. He was nicknamed il Trombone, an ugly or jocular name for someone "who likes to blow his own horn." Born in Milan, he founded a dance academy there in 1554. He was an active court choreographer for the nobility in Milan. He wrote Le Grazie d'Amore, the first text on ballet theory to expound the principle of the "five basic positions". It was republished in 1604 as Nuove lnventioni di Balli (New Inventions of the Dance).
