The Rudrón Valley (Spanish: Valle del Rudrón) is a valley of the province of Burgos, in the autonomous community of Castilla y León, Spain, that borders the autonomous community of Cantabria.

From a structural standpoint, the relief is organized around a large morphostructural unit: an extensive moorland.
