The Voisin Icare Aero-yacht was an early flying boat built by Voisin Frères for the oil magnate and promoter of early aviation experimentation Henry Deutsch de la Meurthe.

It was initially built as a four-bay unequal-span biplane.

A 200 hp (150 kW) Clerget engine drove a four bladed pusher configuration propeller mounted mid-gap via a chain.

It carried six passengers, and had provision for an armament of two cannon.

It was first flown as a landplane on 23 November 1912 at Issy-les-Moulineaux[1] with the full complement of six passengers.
