The Karakoram Highway (KKH) is the highest paved international road in the world. It connects China and Pakistan across the Karakoram mountain range, through the Khunjerab Pass, at an altitude of 4,693 m/15,397 ft as confirmed by both SRTM and multiple GPS readings. It connects China's Xinjiang region with Pakistan's Gilgit-Baltistan and Khyber Pakhtunkhwa regions and also serves as a popular tourist attraction. Due to its high elevation and the difficult conditions in which it was constructed, it is also referred to as the "Ninth Wonder of the World."

The Karakorum Highway is known informally as the KKH, and — within Pakistan — officially as the N-35; within China, officially as China National Highway 314 (G314).
