Luna Fernández Grande

Luna Fernández Grande, also called Luna Fernández (born 1989), is a Spanish female terrorist who, in 2014, traveled to Syria and joined the Islamic State of Iraq and the Levant with her husband and children. She was repatriated to Spain in 2023, and in 2025 she was sentenced to three years in prison for integration into a terrorist organization.

Background and life in ISIL Fernández Grande was born to a 15-year-old mother in Madrid in 1989. Her father was Moroccan and abandoned her when she was four, and at the same age she was taken from her mother by social services. She grew up in care homes, visiting her mother on weekends, and only met her father a few times. after which her personality and behavior changed. Previously an atheist, she converted to Islam and became devoted to the religion. A friend of hers said she "suddenly turned into an Islamic fanatic, applying all of the clichés of that religion to her lifestyle."

The last time Fernández Grande's mother heard from her was in 2013, when she moved to Egypt for a year. She gave birth to a third child there, but the baby died a short time later. The women were detained on arrival on charges of joining a terror organization. The investigation established Fernández Grande in fact supported her husband's decision to take the family to Syria and ISIL, and that her husband had played a larger role in ISIL than she had said. Fernández Grande herself had also "played a key role" and "exercised leadership" of woman members in a terrorist group called the Al Andalus Brigade prior to joining ISIL, and had indocrinated her children in ISIL's ideology.

She spent nearly two years in jail in Spain awaiting trial, before reaching a plea agreement with the prosecution in April 2025, pleading guilty to integration into a terrorist organization. Fernández Grande was sentenced to three years in prison and required to complete a terrorist deradicalization program. Her children were placed in the care of social services. In December 2025, she was ordered to serve the remainder of her sentence under a "third penitentiary regime", which allows her to leave prison during the day from Monday to Thursday and return only to spend the night. Fernández Grande hopes to regain custody of her children.
