Wilmington International Airport (IATA: ILM, ICAO: KILM, FAA LID: ILM) is a public airport located just north of Wilmington, North Carolina, in unincorporated Wrightsboro. ILM covers 1,800 acres (728 ha).

During the calendar year of 2024, ILM served a record-high number of passengers, with 736,868 enplanements and 729,001 deplanements, totaling 1,465,869 passengers. The airport has two runways and a single terminal which has eight gates. The airport is also home to two fixed-base operators (FBO). There is a 24-hour U.S. Customs and Border Protection ramp, built in 2008, for international flights wishing to stop at the airport. The separate terminal was built to serve the international flights that land each year (private or charter). The airport's location on the coast, halfway between New York City and Miami, makes it a desirable and less busy entry point to the United States.

The airport is an operating base for Avelo Airlines.

Wilmington International Airport is owned by New Hanover County, which leases the airport to the Wilmington Airport Authority.
