Kaharingan is an indigenous animistic folk religion of the Dayak people such as Katingan, Lawangan, Ma'anyan, Ngaju, Ot Danum, and Meratus peoples, native to the provinces of Central Kalimantan and South Kalimantan in Indonesia.
The word means something like Way of the life, and this belief system includes a concept of many deities and often one supreme deity—although this may be the result of the need to conform to the idea of "One Supreme God" (Ketuhanan yang Maha Esa), which is the first principle of the Indonesian state ideology Pancasila. The influence of Hinduism can also be seen in this religion. Before 2017, the Indonesian government viewed it as a form of Folk Hinduism because the Indonesian government at that time recognized only six official religions, and Kaharingan was not one of them. However, since November 2017, the government started to formally recognize Aliran Kepercayaan, a broadly defined group of native religions, which also includes Kaharingan.
