The Cerretani or Ceretani were an ancient pre-Roman people of the Iberian Peninsula who occupied what became the modern-day Cerdanya, in the valley Segre and part of Aragon. Their neighbours from the east were Ausetani and from the south Ilergetes. Their capital was Julia Libyca, modern Llívia.[1] They are noted in Greek and Roman geographical treatises.[2]
