The gens Orbia was a minor plebeian family at Rome.
The most illustrious of the family may have been the jurist Publius Orbius, a contemporary of Cicero.
[1] The nomen Orbius is derived from the cognomen Orbus, a waif or orphan.
[5] The Orbii used a wide variety of praenomina, of which the most important were Marcus and Lucius.
The family also used Publius and Titus, and there are few examples of Gaius, Aulus, and Quintus.
