Ampanang is an Austronesian language spoken at the village of Ampanang (no longer exists today), at the Kahala river (flowing into Lake Semayang and eventually the Mahakam), East Kalimantan. It is closely related to Tunjung, forming the Mahakam languages.[2] This language is only known from a small vocabulary list on S. C. Knappert's work Beschrijving van de Onderafdeeling Koetei (1905), and it had been already displaced by or mixed with Kutainese or Malay among the younger generation.[3]
Christian missionary sites claim that Ampanang people live in Jambuk and Lemper (Bongan, West Kutai), thus conflicting with the information provided by S. C. Knappert.[4]
