Milan Bergamo Airport (IATA: BGY, ICAO: LIME), also formerly known as Orio al Serio International Airport, is the third-busiest international airport in Italy. The airport is also officially called Il Caravaggio International Airport after the Baroque painter Michelangelo Merisi da Caravaggio, who originally hailed from the nearby town of Caravaggio.

The airport served almost 17.4 million passengers in 2024 and is one of Ryanair's four largest operating bases, along with Dublin Airport, London Stansted Airport, and Brussels South Charleroi Airport.

The airport is located in Orio al Serio, 3.7 km (2.3 mi) southeast of Bergamo and 45 km (28 mi) northeast of Milan. Together with Milan Malpensa Airport and Milan Linate Airport, it forms the Milan airport system serving the Milan metropolitan area, that with 56.9 million passengers in 2024 constitutes the largest airport system in Italy by number of passengers.

In 2024, Milan Bergamo Airport launched a digital twin initiative to simulate airport operations in real time and support infrastructure planning and emergency management.
