Annia Aurelia Galeria Lucilla (March 7, 150–183) was the daughter of the Roman Emperor Marcus Aurelius and Faustina the Younger.

In AD 164, she was betrothed by her father to his co-emperor and adoptive brother, Lucius Verus, gaining the title of Augusta. Following his death she married Tiberius Claudius Pompeianus. Lucilla was implicated in several plots to overthrow Commodus (her brother and then emperor) and was banished to the island of Capreae in AD 182. Shortly afterwards she was put to death by Commodus.

In the movie Gladiator she was played by Connie Nielsen, and in the earlier Fall of the Roman Empire by Sophia Loren.
