The gens Fonteia was a plebeian family at ancient Rome. Members of this gens are first mentioned toward the end of the third century BC; Titus Fonteius was a legate of Publius Cornelius Scipio during the Second Punic War. The first of the Fonteii to obtain the consulship was Gaius Fonteius Capito, consul suffectus in 33 BC.[1][2]
