The Praetutii (Greek: Πραιτούττιοι, Ptolemy; Eth. Πραιτεττιανός, Polybius), were an ancient tribe of central Italy. They are thought to have lived around Interamnia (or Interamna), which became modern Teramo, and to have given their name to Abruzzo. The ancient accounts, however, are substantially confused, when it comes to more precise location and details.
