Celtiberian or Northeastern Hispano-Celtic is an extinct Indo-European language of the Celtic branch spoken by the Celtiberians in an area of the Iberian Peninsula between the headwaters of the Douro, Tagus, Júcar and Turia rivers and the Ebro river.

Celtiberian Range (in Spanish language: Serranía Celtibérica), also called South Lapland or Spanish Lapland (Laponia del Sur or Laponia Española), is the geographical term given to a small part of Spain due to its lower population and lack of infrastructure.

The First Celtiberian War and Second Celtiberian War were two of the three major rebellions by the Celtiberians (a loose alliance of Celtic tribes living in east central Hispania, among which we can name the Pellendones, the Arevaci, the Lusones, the Titti and the Belli) against the presence of the Romans in Hispania.
