Wakhan Corridor is commonly used as a synonym for Wakhan, an area of far north-eastern Afghanistan which forms a land link or "corridor" between Afghanistan and China. The Corridor is a long and slender panhandle or salient, roughly 140 miles (220 km) long and between 10 and 40 miles (16 and 64 km) wide. It separates Tajikistan in the north from Pakistan in the south.

The corridor was a political creation of the Great Game. On the corridor's north side, agreements between Britain and Russia in 1873 and between Britain and Afghanistan in 1893 effectively split the historic area of Wakhan by making the Panj and Pamir Rivers the border between Afghanistan and the Russian Empire. On its south side, the Durand Line agreement of 1893 marked the boundary between British India and Afghanistan. This left a narrow strip of land as a buffer between the two empires, which became known as the Wakhan Corridor in the 20th century. The corridor has 12,000 inhabitants.

The term Wakhan Corridor is also used in a narrower sense to refer to the route along the Panj River and the Wakhan River to China, and the northern part of the Wakhan is then referred to as the Afghan Pamir.
