Lombardy is an administrative region of Italy that covers 23,844 km2 (9,206 sq mi); it is located in northern Italy and has a population of about 10 million people, constituting more than one-sixth of Italy's population. Lombardy is located between the Alps mountain range and tributaries of the river Po, and includes Milan, its capital, the largest metropolitan area in the country, and among the largest in the EU.

The Lombard language belongs to the Gallo-Italic group within the Romance languages and is characterized by a Celtic linguistic substratum and a Lombardic linguistic superstratum and is a cluster of homogeneous dialects that are spoken by millions of speakers in Northern Italy and southern Switzerland, including most of Lombardy and some areas of the neighbouring regions, notably the far eastern side of Piedmont and the extreme western side of Trentino, and in Switzerland in the cantons of Ticino and Graubünden. The language is also spoken in Santa Catarina in Brazil by Lombard immigrants from the Province of Bergamo, in Italy.
