Calatañazor is a municipality located in the province of Soria, Castile and León, Spain. According to the 2010 census, the municipality has a population of 70 inhabitants. The municipality is named after the tiny fortified city on top of a hill.
Also situated in the municipality are the hamlets Aldehuela and Abioncillo. Abioncillo used to be abandoned like many forsaken hamlets in Spain, but in the 1980s was turned around by a few dedicated teachers into an educational center.
In the valley between Calatañazor and Abioncillo, the Battle of Calatañazor took place in 1002. This place is still named El valle de la sangre.
