The gens Rufinia was an obscure plebeian family at ancient Rome.
Few members of this gens are mentioned in history, although the derivative surname Rufinianus appears in several sources.
[1][2] The nomen Rufinius belongs to a class of gentilicia formed from surnames ending in -inus, using the suffix -inius.
[3] The name was formed from the cognomen Rufinus, reddish, a diminutive of Rufus, red, and in this way is related to a number of other gentilicia formed from rufus, ruber, and rutilus, all with similar meanings, and in most cases originally applied to someone with red or reddish hair.
[4] The Rufinii used a number of common praenomina, including Gaius, Titus, Marcus, Publius, and Lucius.
