Montilla-Moriles is a Spanish Denominación de Origen Protegida (DOP) for wines located in the southern part of the province of Córdoba. It is bounded by the river Genil to the east, by the river Guadajoz to the west, by the river Guadalquivir to the north, and by the Subbetic Range of mountains to the south.

In Spain, the denominación de origen is part of a regulatory geographical indication system used primarily for foodstuffs such as cheeses, condiments, honey, and meats, among others. In wines, it parallels the hierarchical systems of France (1935) and Italy (1963), although Rioja (1925) and Jerez (1933) preceded the full system. In foods, it performs a similar role, regulation of quality and geographical origin of products from Spain. There are five other designated categories solely for wine and a further three specifically covering food and condiments, all recognised by the European Union (EU). In Catalonia, two further categories – labelled A and Q – cover traditional Catalan artisan food products, but were not recognised by the EU as of 2007. In recent decades, the concept of the denominación de origen has been adopted by other countries, primarily in Latin America. In 2016, the use of the Denominación de Origen (DO) for wines was registered as a European Union Protected Designations of Origin/Denominación de Origen Protegida (PDO/DOP), but the traditional Portuguese term of DO can still be used legally on labels.
