Jacques Defermon des Chapelieres (15 November 1752 - 20 July 1831) was a French statesman during the French Revolution and a supporter of Napoleon Bonaparte and the French Empire.In some sources his baptismal names are given as Jacques, Joseph (most probably in error); his surname also spelled as (de) Fermon or (de) Fermond. He can also be referred to as comte Defermon, comte de l'Empire (count Defermon, count of the Empire) from 23 March 1808.
