The flute is a family of a musical instrument in the woodwind group. Unlike woodwind instruments with reeds, a flute is an aerophone or reedless wind instrument that produces its sound from the flow of air across an opening. According to the instrument classification of Hornbostel–Sachs, flutes are categorized as edge-blown aerophones.

Flûte (from the cognate French for flute) can refer to :

• a type of Baguette bread
• a naval ship en flûte

En flûte (French: "as a fluyt") is a French naval expression of the Age of Sail to designate a warship used as a transport, with a reduced armament.
