The Eurocopter AS365 Dauphin (Dolphin), also formerly known as the Aérospatiale SA 365 Dauphin 2, is a medium-weight multipurpose twin-engine helicopter produced by Airbus Helicopters. It was originally developed and manufactured by French firm Aérospatiale, which was merged into the multinational Eurocopter company during the 1990s, and since 2014 Eurocopter was renamed Airbus Helicopters. Since entering production in 1975, the type has been in continuous production for more than 40 years, with the last delivery in 2021. The intended successor to the Dauphin is the Airbus Helicopters H160, which entered operational service in 2021.

Aérospatiale was a major French state-owned aerospace corporation that developed and manufactured both civilian and military aircraft as well as rockets, missiles and satellites. It was incorporated in 1970 as Société Nationale Industrielle Aérospatiale through the merger of three state-owned aerospace companies: Sud Aviation, Nord Aviation and SEREB. The company was headquartered in the 16th arrondissement of Paris.
