Jean La Brunière de Médicis (3 November 1791 in Bordeaux – 5 April 1837 in Paris), known by the stage name of Ferdinand, was a French ballet dancer.

One of the partners of Lise Noblet, his notable appearances with her included a tour to London in 1824.

In 1826, the author of the Nouvelle biographie théâtrale wrote an acid portrait of Ferdinand: Ferdinand, of the Opéra, one day said to his comrade, M. Paul : I bet I jump higher than you.

Seeing that he would lose his reputation for going from low to high and high to low, he began to flit from right to left and left to right, and the volubility of his legs was such that they could not be seen, and M. Paul gave himself sprains wanting to imitate him.

Since then, M. Ferdinand sets the air alight here and there, and is becoming, more and more, the scourge of flies which he murders by the thousand.
