Traditional Thai musical instruments (Thai: เครื่องดนตรีไทย, RTGS: Khrueang Dontri Thai) are the musical instruments used in the traditional and classical music of Thailand. They comprise a wide range of wind, string, and percussion instruments played by both the Thai majority as well as the nation's ethnic minorities.

In the traditional Thai system of organology, they are classified into four categories, by the action used in playing:

1. Plucking (plucked string instruments; เครื่องดีด, khrueang dit)
2. Bowing (bowed string instruments; เครื่องสี, khrueang si)
3. Striking (percussion instruments and hammered dulcimer; เครื่องตี, khrueang ti)
4. Blowing (wind instruments; เครื่องเป่า, khrueang pao)
