Pla de Bages is a Spanish Denominación de Origen Protegida (DOP) (Denominació d'Origen Protegida in Catalan) for Catalan wines, located in the province of Barcelona (Catalonia, Spain), and is one of the smallest DOPs in Spain, covering less than 500 hectares.

In wine-making contexts the name of Bages is often said to derive from an otherwise unnoted ancient Roman city of Bacassis located in the area.

There are two different types of soil in two well-defined topographies: a central basin (Pla de Bages) with clay and marl soils at an altitude of 200 m above sea level; and a peripheral area (Alt Bages, "Upper Bages") where marl and lime bearing soils with a high carbonate content abound, at an altitude of 500 m above sea level.

The climate is Mediterranean with strong continental influences due to its inland location quite far from the sea.

Humidity is lower, summers hotter and winters colder than in other wine-producing areas in Catalonia.
