Annia Aurelia Galeria Lucilla or Lucilla (March 7, 148 or 150 – 182) was the second daughter and third child of Roman Emperor Marcus Aurelius and Roman Empress Faustina the Younger.
She was the wife of her father's co-ruler Lucius Verus and an elder sister to later Emperor Commodus.
Commodus ordered Lucilla's execution after a failed assassination and coup attempt when she was about 33 years old.
