Pomponia Graecina (d. 83 AD) was a noble Roman woman of the 1st century who was related to the Julio-Claudian dynasty. She was the wife of Aulus Plautius, the general who led the Roman conquest of Britain in 43 AD, and was renowned as one of the few people who dared to publicly mourn the death of a kinswoman (Julia Livia, granddaughter of emperor Tiberius) killed by the Imperial family. It has been speculated that she was an early Christian. She is identified by some as Lucina or Lucy, a saint honoured by the Roman Catholic Church.
