Tinkar Valley is a Himalayan valley situated in the Darchula District in the Sudurpashchim Province of Nepal. Located in the northwestern corner of Nepal at an elevation of 3,650 metres (11,980 ft), it borders Tibet region of China in the north and India's Uttarakhand state in the west. It houses the river Tinkar Kohla, which drains into the Mahakali River near the village of Chhangru. Tinkar is the name of the other large village in the valley.
At the top of the Tinkar valley near the Tibet border is the Tinkar Pass (5,258 m), which provides a trading route for the Byansis of the region for the Tibetan trading centre Burang. However, the Tinkaris are said to prefer the Lipulekh Pass across the border in Indian territory due to its higher volume. Nepal has ongoing claims to the Lipulekh Pass, as part of the Kalapani territory dispute.
