Jean-Claude Petit (born 14 November 1943) is a French composer and arranger, born in Vaires-sur-Marne. After accompanying jazzmen in his childhood, Petit went to the Conservatoire de Paris, where he studied harmony and counterpoint. He did the string arrangements for Mink DeVille's Le Chat Bleu album, as well as orchestrating the backing parts to some French pop singles in the mid-to-late 1960s, including those of Erick Saint-Laurent and yé-yé girls Christine Pilzer and Monique Thubert.

In 1973 he composed La leçon de Michette, a delicious, short song: it was so famous in Italy, because it had been used for a soundtrack of a well-known Carosello (the Italian TV spot broadcast) from 1973 to 1976.
