Lucius Pomponius Flaccus (died 33) was a Roman senator, who held a number of imperial appointments during the reign of Tiberius. He was consul in AD 17 with Gaius Caelius Rufus as his colleague.[1]
Flaccus was the brother of Gaius Pomponius Graecinus, consul the year before in 16. Either he or his brother may have married Vistilia, mother of Milonia Caesonia, the wife of Caligula, and had two sons: Publius Pomponius Secundus and Quintus Pomponius Secundus.
