Klong khaek (Thai: กลองแขก, pronounced [klɔːŋ kʰɛ̀ːk]) is a type of double-headed barrel drum used in Thai music.
There are two types of klong khaek: klong khaek tua phu (Thai: กลองแขกตัวผู้) which is considered to be male, and klong khaek tua mia (Thai: กลองแขกตัวเมีย) regarded as female.
The two drums fit their beats together in hocket, or interlocking form.
Both drumheads are played with the hands, like the klong songna.
The klong khaek tua phu has a higher pitch and the klong khaek tua mia has a lower pitch.
