Myrtle Beach International Airport (IATA: MYR, ICAO: KMYR, FAA LID: MYR) is a county-owned public-use airport located 3 miles (5 km) southwest of the central business district of Myrtle Beach, in Horry County, South Carolina, United States. It was formerly known as Myrtle Beach Jetport (1974–1989) and is located on site of the former Myrtle Beach Air Force Base, which also includes The Market Common shopping complex.

The Federal Aviation Administration (FAA) National Plan of Integrated Airport Systems for 2017–2021 categorized it as a small-hub primary commercial service facility. Myrtle Beach has the second-busiest airport in South Carolina behind Charleston, with over 2.4 million passengers (arriving and departing) in 2018.

The airport's official website since 2006 is flymyrtlebeach.com, which was previously an unofficial website owned by an airport employee. In July 2012 the airport launched a redesigned website with a new logo.
