Lancaster Airport (IATA: LNS, FAA LID: KLNS, TC LID: LNS) is a public use airport four nautical miles (5 mi, 7 km) north of the central business district of Lancaster, in Lancaster County, Pennsylvania, United States. It is owned by the Lancaster Airport Authority. It is served by one commuter airline subsidized by the Essential Air Service program and one charter airline.

The National Plan of Integrated Airport Systems for 2021–2025 categorized it as a general aviation airport based on enplanements in 2008 (less than 2,500 per year); however, it qualifies as a non-primary commercial service airport based on yearly enplanements in later years.
