100 Nights of Hero is a 2025 historical fantasy romance film written and directed by Julia Jackman, based on the graphic novel The One Hundred Nights of Hero by Isabel Greenberg, which itself was based on the Middle Eastern folktale One Thousand and One Nights. It stars Emma Corrin, Nicholas Galitzine, Maika Monroe, Amir El-Masry, Charli XCX, Richard E. Grant and Felicity Jones. It follows a woman (Monroe) whose neglectful husband (El-Masry) leaves her alone for a hundred days to test her fidelity, as she becomes entangled in a love triangle with her loyal maid (Corrin) and her husband's seductive friend (Galitzine).

The film had its world premiere in the Settimana Internazionale della Critica section of the 82nd Venice International Film Festival on 6 September 2025, and was the Closing Night film of the 2025 BFI London Film Festival. It was released in the United States on 5 December 2025 by Independent Film Company and in the United Kingdom and Ireland in early 2026 by Vue Lumière.
