The Croses Pouplume ("lousefeather") was an unusual ultralight aircraft developed in France in the 1960s.

It was inspired by Henri Mignet's Pou-du-Ciel design with its distinctive tandem wing layout.

Croses set out to develop a similar aircraft, to be powered by a single-cylinder motorcycle engine of around 6 kW (8 hp).

Like the Pou-du-Ciel, the Pouplume dispensed with traditional ailerons and elevators, and pivoted the entire forward wing to provide pitch control.

A further development, the Pouplume Sport was designed to be powered by a 1500 cc Volkswagen air-cooled engine, and featured wings of reduced span.
