Bergamo is a city in the alpine Lombardy region of northern Italy, approximately 40 km (25 mi) northeast of Milan, and approximately 30 km (19 mi) from Switzerland, the alpine lakes Como and Iseo, and 70 km (43 mi) from Garda and Maggiore. The Bergamo Alps (Alpi Orobie) begin immediately north of the city.

With a population of approximately 122,000, Bergamo is the fourth-largest city in Lombardy. Bergamo is the seat of the Province of Bergamo. The metropolitan area of Bergamo extends beyond the administrative city limits, spanning over a densely urbanized area with slightly fewer than 500,000 inhabitants. The Bergamo metropolitan area is part of the broader Milan metropolitan area, home to more than eight million people.

The city of Bergamo is composed of an old walled core, known as Città Alta ("Upper Town"), nestled within a system of hills constituting a regional park, and the modern expansion in the plains below. The upper town is encircled by massive Venetian defensive systems that are a UNESCO World Heritage Site since 9 July 2017.

Bergamo is well connected to several cities in Italy, thanks to the motorway A4 stretching on the axis between Turin, Milan, Verona, Venice, and Trieste. The city is served by Il Caravaggio International Airport, the third-busiest airport in Italy with 13.9 million passengers in 2019. Bergamo is the second most visited city in Lombardy after Milan.
