Two notable Romans of the gens Fulvia were named Quintus Fulvius Flaccus.

Quintus Fulvius Flaccus, son of the first Marcus Fulvius Flaccus, was consul in 237 BC, fighting the Gauls in northern Italy. He was censor in 231, again consul in 224, when he subdued the Boii. He was a praetor in 215 and in the following year, and Master of Horse in 213.

Consul again 212, fighting the Second Punic War, he won a victory over Hanno the Great, capturing his camp at Beneventum, then captured Capua in 211 while serving as proconsul. In his fourth term as consul, (209) he retook Lucania and Bruttium. He opposed the African expedition of Scipio Africanus Major in 205, and died sometime not long thereafter.

His son Quintus Fulvius Flaccus is first noticed as curule aedile in 184 BC, then as praetor in Spain campaigning against the Celtiberians in 182-180. As consul in 179 he fought the Ligurians. He was censor in 174, and in 173 built a temple to Fortuna Equestris by taking marble from a temple of Hera Lacinia in Croton. He was reported to have gone insane the following year and committed suicide. The Via Fulvia is doubtfully attributed to him.
