Data from FlightRadar showed about a dozen planes were forced to circle above the airport before being given permission to land.
The temporary closure came two months after a similar situation caused pre-Christmas travel chaos for hundreds of thousands of passengers at London’s Gatwick Airport.
In December, Gatwick officials had to shut the runway several times over three days after repeated sightings of a drone.
The chaos was less severe at Dublin Airport with the runway reopening less than an hour after closing.
Flights were delayed for more than half an hour and the knock-on effect will cause mayhem for flyers throughout the rest of the day.
The first flight to take off after the runway reopened was the 11.30am Ryanair flight to Eindhoven which finally departy at 12.06pm.
In a statement, Dublin Airport said: “For safety reasons we are temporarily suspending flight operations at the airport due the confirmed sighting of a drone over the airfield.
The airport added: “Passengers should contact their airline’s website for flight updates.
“We will post updates here when they become available.
“The safety and security of customers is our key priority at all times.”
