The flute is a family of musical instruments 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. A musician who plays the flute is called a flautist or flutist.

Flutes are the earliest known identifiable musical instruments, as paleolithic examples with hand-bored holes have been found. A number of flutes dating to about 43,000 to 35,000 years ago have been found in the Swabian Jura region of present-day Germany. These flutes demonstrate that a developed musical tradition existed from the earliest period of modern human presence in Europe.

While the oldest flutes currently known were found in Europe, Asia, too, has a long history with the instrument that has continued into the present day. In China, a playable bone flute was discovered, dated approximately 9000 years old. The Americas also had an ancient flute culture, with instruments found in Caral, Peru, dating back 5000 years and in Labrador dating back approximately 7500 years.
