El Prat de Llobregat, commonly referred to as El Prat, is a municipality located in the comarca of Baix Llobregat within the Catalonia region of Spain. It serves as an integral component of the broader Barcelona metropolitan area.
The municipality is most notably characterized by its geography and infrastructure, as the Josep Tarradellas Barcelona–El Prat Airport is situated largely within its municipal limits. This proximity to the airport defines much of the area's logistical significance within the region.
