Berenguela (or Berengaria) (1180-November 8, 1246), was briefly queen of Castile and León. Daughter of Alfonso VIII of Castile and Leonora of Aquitaine, she married Alfonso IX in 1198, but this was annulled later by the pope because they were second cousins.

When her brother Henry died by accident in 1217, Berenguela renounced her rights to the throne, in favor of her son Ferdinand.
