The Kalapani territory is an area under Indian administration as part of Pithoragarh district in the Kumaon Division of the Uttarakhand state, but it is also claimed by Nepal since 1997. According to Nepal's claim, it lies in Darchula district, Sudurpashchim Province. The territory represents part of the basin of the Kalapani river, one of the headwaters of the Kali River in the Himalayas at an altitude of 3600–5200 meters.
