The gens Ostoria, occasionally written Hostoria, was a plebeian family at Rome.
The most illustrious of the Ostorii was probably Publius Ostorius Scapula, who was consul during the reign of Claudius, and afterward governor of Britain.
[1][2] The main praenomina of the Ostorii were Quintus, Publius, Marcus, Gaius, and Lucius, which were the five most common names throughout Roman history.
The cognomina of the Ostorii occurring in ancient historians were Sabinus and Scapula.
[3] The Scapulae were the only important family of the Ostorii, holding four consulships over the course of the first century.
