Rhodes International Airport, "Diagoras" or Diagoras International Airport (IATA: RHO, ICAO: LGRP) is located on the West side of the island of Rhodes in Greece. The facility is located just north of the village Paradisi, about 14 km southwest of the capital city, Rodos.

Rhodes International Airport was the fourth busiest airport in Greece as of 2014, with 4,552,955 passengers utilizing the airport.

Civil aviation on Rhodes started after the second world war, on the location of the nearby military Rhodes Maritsa Airport. This was the island's main airport until 1980, when the new Rhodes International Airport was opened. The need for a new facility was big, as the 'old' Maritsa airport did not meet the needs for a modern civil airport.

The new "Diagoras" airport was built in 1977. It was decided that, on this location, it would meet the needs of the island better.

Over the passing years, many improvements have been made to the airport, like expansion of taxiways, platform and airport buildings. The most recent upgrade is the new passenger terminal, which opened in 2005, to better accommodate the growing amount of charters and passengers. The airport's plants currently cover a total area of 60,000 m2.
