Opiter Verginius Tricostus served as consul of the early Roman Republic in 502 BC, with Spurius Cassius Viscellinus. He was the first from the powerful Verginia family to obtain the consulship.
Together with his colleague Spurius Cassius Viscellinus, Verginius Tricostus fought against the Aurunci, and took Pometia.Livy also says that the consuls celebrated a triumph for their victory, however the Fasti Triumphales record only one triumph, by Cassius.
The filiation of a number of consular men in the following generation suggests they were Opiter Verginius' sons. They are: Proculus Verginius Tricostus Rutilus (consul 486 BC), Titus Verginius Tricostus Rutilus (consul 479 BC), Opiter Verginius Tricostus Esquilinus (consul 478 BC) and Aulus Verginius Tricostus Rutilus (consul 476 BC).
