POxy 1464 (or P. Oxy. XII 1464) is a document that was found at the city of Oxyrhynchus in Egypt. This document was given to a Roman citizen to certify performance of a pagan sacrifice, hence demonstrating loyalty to the authorities of the Roman Empire. Such a document is called a libellus (plural libelli), and this was one of four libelli found at Oxyrhynchus.
