Gorgonzola is a town in the Metropolitan City of Milan, Lombardy, northern Italy. It is part of the territory of the Martesana, north-east of Milan. Gorgonzola cheese is named after the town.

Gorgonzola is a veined protected designation of origin (PDO) Italian blue cheese, made from unskimmed cow's milk. It can be buttery or firm, crumbly and quite salty, with a "bite" from its blue veining. Outside the EU and the countries recognizing the geographical origin protection, the name "Gorgonzola" can legally be used for similar cheeses, with only the full Italian name unambiguously referring to PDO Gorgonzola. It is a famously pungent cheese.
