Plautia Urgulanilla (fl. 1st century) was the first wife of the future Roman Emperor Claudius. They married sometime around the year 9 CE, when Claudius was 18 years old. According to Suetonius, Claudius divorced her in 24 on grounds of adultery by Plautia and his suspicions of her involvement in the murder of her sister-in-law Apronia.
Urgulanilla had a daughter, Claudia, who was born five months after her divorce from Claudius. As Claudia was widely known to be the illegitimate daughter of the freedman Boter, Claudius repudiated the child and he had her laid at Urgulanilla's doorstep. Her adopted nephew was Tiberius Plautius Silvanus Aelianus.
Urgulanilla appears as a significant character in Robert Graves I, Claudius. Urgulanilla is a tremendous and bulky woman with a resemblance to Tiberius (who may possibly be her father). She utterly despises Claudius but is relatively ignorant and benign to her husband. She also bears a strong affection for her sister-in-law Numantina, which causes her to kill her brother's second wife. Claudius apathetically divorces Urgulanilla following this suspicion of murder and the revelation that his wife has a child with her slave. While ordered to execute the child Claudius spares it by substituting the baby with a stillborn child to display for repudiation. Urgulanilla later gives Claudius several gifts in her will (prior to his rise to Emperor) and insists that Claudius is not an idiot. Comparatively Urgulanilla proves to be Claudius' best wife as she leaves Claudius on his own and is not openly cruel or manipulative to him.
