Alcyone is a ship launched at La Rochelle in 1985 for the Cousteau Society. Alcyone was created as an expedition ship and to test the operation of a new kind of marine propulsion system, the turbosail. Alcyone's two turbosails augment its diesel engines. Since the accidental sinking of Calypso, Alcyone has been the Cousteau Society's expedition vessel.

• John Denver wrote a short song called "Alcyone The Wind" as a tribute to Alcyone. The song was sung in the 1993 documentary Secret Societies of Dolphins and Whales.
