Joseph Joubert Charles La Bastide, knight and marquis of Chateaumorand (or Château-Morand), was a naval officer and colonial administrator French in the seventeenth and eighteenth centuries.

He was a governor of Saint-Domingue between 11 January 1717 and 10 July 1719, and Lieutenant-General of the Naval Armies (1 November 1720).

Among his siblings, two are distinguished in the service of the armies of the king of France: Francis Annet Joubert de la Bastide, Marquis of Chateaumorand, and captain, and Jean Francois Joubert La Bastide, Marquis of Chateaumorand, Lieutenant General of the armies of King and head of St. Louis.

D'Iberville returned to France in 1697, where he was selected by the Ministry of the Navy at the head of an expedition to rediscover the mouth of the Mississippi and Louisiana to colonize the coveted British.

After three months at sea, they reached the island of Santa Rosa's face, in Pensacola, Florida, on 25 January 1699, a Spanish city.
