Dassault Aviation SA (French pronunciation: ​[daˈso]) is an international French aircraft manufacturer of military, regional, and business jets, and is a subsidiary of Dassault Group.

It was founded in 1929 by Marcel Bloch as Société des Avions Marcel Bloch or "MB". After World War II, Marcel Bloch changed his name to Marcel Dassault, and the name of the company was changed to Avions Marcel Dassault on 20 January 1947.

In 1971 Dassault acquired Breguet, forming Avions Marcel Dassault-Breguet Aviation (AMD-BA). In 1990 the company was renamed Dassault Aviation.
