Lucifer, as a figure from mythology and religion, does not have a daughter in traditional lore. However, in modern interpretations, such as in fantasy literature, TV series, and other creative works, Lucifer might be depicted with a daughter.
If you're interested in a specific fictional portrayal of Lucifer, it's helpful to know the source material. For example, in the TV series Lucifer, Lucifer does not have a biological daughter, but he does have a son, named Rory.
