Matsu Nangan Airport (IATA: LZN, ICAO: RCFG) is a small regional airport serving Nangan Island, the largest island of the Matsu Islands archipelago administered by Lienchiang County, Taiwan. It provides essential air connectivity for residents and visitors to this remote island group located near the coast of Fujian Province, China. The airport operates short runway facilities suitable for turboprop aircraft, handling a limited number of daily flights primarily to and from Taipei's Songshan Airport and Taichung. Due to the island's frequent fog and challenging weather conditions, flights are often delayed or cancelled, making reliability a persistent challenge for travelers. Despite its limitations, the airport plays a critical role in the socioeconomic life of the Matsu Islands, as it supplements ferry services which are also subject to weather disruptions. The facility is modest in scale, reflecting the small permanent population of Nangan Island.
