Claudia Antonia (Classical Latin: ANTONIA•CLAUDII•CAESARIS•FILIA) (c. AD 30–AD 66) was the daughter of the Roman Emperor Claudius and his second wife Aelia Paetina. Antonia was a great great-niece of the Emperor Augustus, great-niece of the Emperor Tiberius, first cousin of the Emperor Caligula, half-sister to Claudia Octavia and Britannicus, cousin, stepsister and sister-in-law of the Emperor Nero.

Until 37, she was raised by her paternal grandmother Antonia Minor (who died that year). From then until 43, she was raised by her father. In 43, she first married Gnaeus Pompeius Magnus, a descendant of Pompeia (daughter of Pompey the Great). His parents were consul Marcus Licinius Crassus Frugi and Scribonia. According to Suetonius Pompeius was stabbed to death several years later (AD 46/47), when he was caught in bed with a favorite boy. Cassius Dio states that the Empress Valeria Messalina, ordered his execution out of fear that Pompeius might become a rival to Britannicus. The death of Pompeius left Antonia free to marry Messalina's half-brother Faustus Cornelius Sulla Felix.

Faustus Sulla and Antonia married in 47. They had a son who was frail and died before his second birthday. In 58, Faustus Sulla was exiled, and in 62 he was murdered at the order of the Emperor Nero. In 65, Tacitus records the rumour that Gaius Calpurnius Piso intended to marry Antonia, as an element of his conspiracy against Nero.
