Nikolayevsk-na-Amure Airport (IATA: NLI, ICAO: UHNN) serves the small city of Nikolayevsk-na-Amure in Khabarovsk Krai, in Russia's far eastern region near the mouth of the Amur River. The airport provides essential air connectivity to this remote settlement, which is largely inaccessible by road for much of the year due to the harsh terrain and climate. The airport operates limited scheduled services, primarily connecting the city to Khabarovsk and other regional centers. Given the area's geographic isolation, aviation is a critical mode of transportation for residents and supplies, especially during winter months when the river freezes and alternative routes are restricted. The facility is modest in scale, reflecting the small population it serves, and handles propeller and turboprop aircraft typical of Russia's regional aviation network.
