Marie-Jules Dupré was a French admiral. He was governor of Réunion from 1865 to 1869 under the Second French Empire, and governor of Cochinchina from 1871 to 1874 under the French Third Republic. He negotiated a treaty with the Emperor of Vietnam that opened up the country to French commerce and ceded territory in the south to France.

Cochinchina or Cochin-China is a historical exonym for part of Vietnam, depending on the contexts. Sometimes it referred to the whole of Vietnam, but it was commonly used to refer to the region south of the Gianh River.
