Sopilka (, ) is a name applied to a variety of woodwind instruments of the flute family used by Ukrainian folk instrumentalists. Sopilka most commonly refers to a fife made of a variety of materials (but traditionally out of wood) and has six to ten finger holes. The term is also used to describe a related set of folk instruments similar to recorder, incorporating a fipple and having a constricted end.
Sopilkas are used by a variety of Ukrainian folkloric ensembles recreating the traditional music of the various sub-ethnicities in western Ukraine, most notably that of the Hutsuls of the Carpathian Mountains. Often employing several sopilkas in concert, a skilled performer can mimic a variety of sounds found in nature, including bird-calls and insects.
