The roneat dek (Khmer: រនាតដែក) is a Cambodian metallophone. It is an ancient instrument made of metal and is used in the pinpeat ensemble. It is believed to have originated from the Royal Courts before the Angkor period. This instrument is rarely covered with ornamentation on either the bars or the sound box. The roneat dek is analogous to the ranat ek lek of Thailand.
