Laguna de Duero is a municipality located in the province of Valladolid, Castile and León, Spain. According to the 2007 census (INE), the municipality has a population of 21,214 inhabitants.

It is the second largest city in Valladolid behind Valladolid City.

Nowadays it is an industrial town situated 7 km away from the capital city of Valladolid. The town has some neighbourhoods distant from the town center like Torrelago or El Villar. The town has three industrial estates, for example, those of Las Lobas or Los Barreros.

The town is surrounded by pine woods and its municipal territory is bathed by the River Douro. What gives a privileged situation to this town, because this made the town into a place rich in wellsprings. However many of them fell into disuse or are abandoned at present. The most important is the Fountain of San Pedro Regalado at the place of El Abrojo.

The name of the town derives from the former enormous salt lagoon which existed in this town. Nowadays only a small portion of it remains in a recently remodelled beautiful environment converted into a park

Laguna de Duero enjoys a Mediterranean continental climate, which is distinct from the Mediterranean sea climate because of the inexistent thermo-regulatory influence from the sea. As a matter of fact, the climate changes are more drastic because of the isolation of the region, which is surrounded by three mountain ranges, and a higher altitude over the sea level.

The Douro's canal was constructed in order to supply water to the City of Valladolid during the 19th century by José María de Salamanca y Mayol in 1879. At present, it is a beautiful natural space and is notable for the large amount of birds flying over.
