Galus Sulpicius (suffect consul 4 BC)  Galus Sulpicius (fl. 1st century BC) was a Roman Senator who was appointed suffect consul in 4 BC with Gaius Caelius as his colleague. Sulpicius was a member of the Patrician "gens Sulpicia", and is believed to be a descendant of Gaius Sulpicius Gallus, the consul of 166 BC. Aside from his appointment as suffect consul in 4 BC, replacing Lucius Passienus Rufus, nothing else is known of his career. He had at least one son, also named Galus Sulpicius, who was a "Triumvir monetalis" in 5 BC.
