Persona Q: Shadow of the Labyrinth is a role-playing video game developed by Atlus for the Nintendo 3DS. It is part of the Persona series, itself part of the larger Megami Tensei franchise.

The story of Persona Q is a crossover between Persona 3 and Persona 4, whose characters are drawn from their respective time periods by an unknown force and sent into a replica of Persona 4's Yasogami High School in another world. Meeting with Zen and Rei, two people whose memories were taken, the groups must unite and explore four labyrinths in the school to recover treasures hidden within which can restore Zen and Rei's memories, and to find a way to escape. The gameplay fuses elements of the Persona and Etrian Odyssey series, and focuses on first-person dungeon crawling through labyrinths and combat using the characters' "Persona" abilities against hostiles known as Shadows.
