Mazongshan Airport is a small regional airport located in Mazongshan, a remote town in the Subei Mongol Autonomous County of Gansu Province, northwestern China. The airport serves a sparsely populated and geographically isolated area near the Gobi Desert and the border with Mongolia. The facility primarily handles limited domestic regional flights, supporting local connectivity in one of China's most remote and least-populated regions. Due to its isolated location and small catchment area, passenger volumes remain very low compared to major Chinese airports.
