The gens Valgia was a minor plebeian family at ancient Rome. Members of this gens are first mentioned in the final century of the Republic. The most illustrious of the Valgii was Gaius Valgius Rufus, a poet contemporary with Horace, who became consul suffectus in 12 BC.^[1]

The nomen Valgius is derived from the surname Valgus, originally indicating someone with bow legs.^[2]

The only cognomen among the Valgii mentioned in Roman authors was Rufus, originally referring to someone with red hair, and belonging to a large class of surnames derived from the physical features of an individual.^[3]

This list includes abbreviated praenomina. For an explanation of this practice, see filiation.
