Annia Aurelia Galeria Faustina (30 November 147-after 165) was the eldest child of the Roman emperor Marcus Aurelius and his wife, Faustina the Younger. Her younger sister was Lucilla and her younger brother was Commodus. Her maternal grandparents were Antoninus Pius and Faustina the Elder, while her paternal grandparents were Domitia Lucilla and praetor Marcus Annius Verus. She was born and raised in Rome.
The parents of Galeria Faustina betrothed her to Gnaeus Claudius Severus, whom she later married after 159. Gnaeus Claudius Severus was a Roman Senator of Pontian Greek descent that came from Pompeiopolis, a city in the Roman province of Galatia. After Galeria Faustina married Claudius Severus, they had settled in Pompeiopolis. Galeria Faustina bore Claudius Severus, a son called Tiberius Claudius Severus Proculus, who served as consul in 200.
