Jacques Coitier (c. 1430 – 22 October 1506) was a French doctor. He was chief physician to Louis XI of France and president of the Chambre des comptes. Coitier was born at Poligny, Franche-Comté. His name is spelled in several ways, most often Coictier (the spelling used by Victor Hugo in his novel The Hunchback of Notre-Dame), but also Coittier, Cotier, Coytier or Coctier. An analysis of his signatures by Achille Chereau has allowed Coitier to become the standard spelling - this was the name cited most often in medical annals. He died in Paris.
