The Oretani or Oretanii (Greek: Orissioi)[1] were a pre-Roman ancient Iberian people (in the geographical sense) of the Iberian Peninsula (the Roman Hispania), that lived in northeastern Andalusia, in the upper Baetis (Guadalquivir) river valley, eastern Marianus Mons (Sierra Morena), and the southern area of present-day La Mancha.
