Wakhjir Pass, Mountain pass in the Wakhan Corridor, Badakhshan Province, Afghanistan

Wakhjir Pass is a broad, shallow saddle between the Hindu Kush and Pamir Mountains at the eastern end of Afghanistan's Wakhan Corridor, on the border with China's Xinjiang. It lies at 4,923 m, with snow-covered upper slopes and bare, stony ground below. China calls it South Wakhjir Pass, as a northern pass exists on its side.

The pass was part of the Silk Road, used as a trade route between Kabul and Kashgar. The pilgrim Xuanzang is believed to have crossed it around 649 AD, and Benedict Goëz crossed from Wakhan to China between 1602 and 1606. In May 1906 Aurel Stein reported about 100 pony loads of goods passing each way annually.

The pass is called Vakhjir Daalaan in Pashto and South Wakhjir Pass (南瓦根基达坂) in Chinese, since a northern pass exists on the Chinese side. The 3.5-hour clock change at the border, from UTC+04:30 to UTC+08:00, is the sharpest of any international frontier.

There is no official border crossing, and the Chinese side is open only to security personnel; a 92 km barbed-wire fence runs along the border, with a Chinese outpost at Keketuluke 20 km east. On the Afghan side the nearest settlement is Sarhad-e Broghil, about 121 km of road travel away, and a gravel road from Sarhad reached the pass by July 2024. The pass is traditionally closed for at least five months a year.

Just below the pass on the Afghan side, at 4,554 m, an ice cave is the source of the Wakhjir River, which reaches the Amu Darya. The cave is therefore claimed as a source of the Amu Darya, and Dilisang Pass toward Pakistan lies about 20 km away in the same valley.
