The Aérospatiale SA 360 Dauphin was a single-engine French utility helicopter developed and produced by aerospace manufacturer Aérospatiale.

It was developed during the early 1970s as a replacement for the company's popular Alouette III helicopter, as well as to fill in an apparent gap in the company's existing product line, falling within the six to ten-seat helicopter category. Performing its maiden flight on 2 June 1972, the prototypes the demonstrated type's performance capacities by setting three world airspeed records for helicopters in the 1,750 kg – 3,000 kg class. The Dauphin was marketed towards both civilian and military customers, however, as the new helicopter supposedly offered little advantage over its predecessor, the type possessed only a limited market appeal and did not sell well.

Ultimately, production of the SA 360 Dauphin was abandoned after only a few dozen of helicopters had been completed. However, Aérospatiale did not give up on the design, subsequently developing a twin-engine derivative of the SA 360, the Dauphin 2, which proved to be commercially successful, having been in production for in excess of 40 years. Following the integration of Aérospatiale's helicopter division into the multinational Eurocopter consortium in 1992, the Dauphin 2 designation was dropped, and Eurocopter-built examples have been simply referred to as "Dauphin". The retronym "Dauphin 1" is sometimes applied to the original Dauphin to distinguish the two.
