The Wakhjir Pass, also spelled Vakhjir Pass, is a mountain pass on the Afghanistan–China border, between the Hindu Kush and Pamir Mountains at the eastern end of the Wakhan Corridor. It is the only potentially navigable pass between Afghanistan and China in the modern era. It links the Wakhan District of Badakhshan Province in Afghanistan with the Tashkurgan Tajik Autonomous County in Xinjiang, China, at an altitude of 4,923 m (16,152 ft). As of 2025, the pass has no official border crossing point. With a difference of 3.5 hours, the Afghanistan–China border has the sharpest official change of clocks of any international frontier (UTC+04:30 in Afghanistan to UTC+08:00, in China). China refers to the pass as South Wakhjir Pass (Chinese: 南瓦根基达坂), as there is a northern pass on the Chinese side.
