Tierra de Campos ("Land of Fields") is a large historical and natural region or greater comarca that straddles the provinces of León, Zamora, Valladolid and Palencia, in Castile and León, Spain.

[1] Despite the strong identity of its inhabitants, this historical region has not been able to achieve the necessary legal recognition for its administrative development.

"Tierra de Campos" is located on a fertile, elevated plateau with an average height of around 720 metres (2,360 ft), its geography is typical of the Meseta Central.

Rivers naturally irrigating the area are sparse and traditionally the land in Tierra de Campos has been used for dryland farming.

The Tierra de Campos is the place with the highest concentration of bustard in the Iberian Peninsula, and possibly in the world.
