Reggio nell'Emilia (Emilian: Rèz; Latin: Regium Lepidi), usually referred to as Reggio Emilia, or simply Reggio by its inhabitants, and known until 1861 as Reggio di Lombardia, is a city in the region of Emilia-Romagna in Italy. With a population of 172,518, it is the 4th-largest city in Emilia-Romagna and the 22nd-largest in Italy.

The inhabitants of Reggio nell'Emilia are called Reggiani, while the inhabitants of Reggio di Calabria, in the southwest of the country, are called Reggini.

The old town has a hexagonal form, which derives from the ancient walls, and the main buildings are from the 16th–17th centuries. The commune's territory lies entirely on a plain, crossed by the Crostolo stream.
