Valles de Sadacia is a Spanish geographical indication for Vino de la Tierra wines located in the autonomous region of La Rioja.

Three types are considered: dry (seco), semi-dry (semiseco or semidulce) and sweet (dulce).

The Valles de Sadacia geographic indication was created in 2003, on the initiative of the Agricultural Authorities of the Government of La Rioja, in collaboration with Castillo de Maetierra, a winery specialized in the production of quality white wine.

[3] The name Sadacia derives from Sádaco, the ancient Roman name of the river Cidacos.

This area receives the lowest rainfall and most hours of sunlight in the La Rioja region.
