Publius Petronius Turpilianus was a Roman politician and general. He was consul in AD 61, but in the second half of that year he laid down that office and was appointed governor of Britain, replacing Gaius Suetonius Paulinus who had been removed from office in the wake of the rebellion of Boudica. In contrast to Suetonius's punitive measures, Petronius took a conciliatory approach, and conducted few military operations. In 63 he was replaced by Marcus Trebellius Maximus, and was appointed curator aquarum (superintendent of aqueducts) in Rome.
