The khlui (, ) is a vertical duct bamboo flute from Thailand, which originated before or during the Sukhothai period (1238–1583). It was officially recognized as a Thai instrument by King Trailokkanat (1431–1488), who set the official model of each traditional Thai instrument. It is generally made of bamboo, though it can also be made from other types of wood or plastic. After many generations of modifications, it survives to the present day in three main forms: the khlui phīang aw, khlui lip, and khlui ū, which are of different sizes, although there are more variations of the khlui, like khlui kruad, khlui rōng-aw and khlui nok. The khlui is very similar to the Cambodian khloy.
