Cyril E. King Airport (IATA: STT, ICAO: TIST, FAA LID: STT) is located two miles (3 km) west of the central business district of Charlotte Amalie on the island of St. Thomas in the United States Virgin Islands. It is one of the busiest in the eastern Caribbean. The airport also serves nearby St. John and is often used by those traveling to the British Virgin Islands.

It was known as Harry S Truman Airport until 1984, when it was renamed to honor Cyril Emmanuel King, the second elected governor of the U.S. Virgin Islands. A new airport opened in November 1990 and retained the name.

The Airport operates one main runway, around 7,000 ft long. Although considered by some to be a relatively short runway, La Guardia Airport has the same length, and has frequent visits by widebody aircraft.
