Atlus West, formerly known as Atlus U.S.A., Inc., is the North American publishing branch of Japanese video game company Atlus, primarily known for localizing games for both them and other third-party developers. Its first original role-playing game was Revelations: Persona on the PlayStation, described by staff as an attempt to break into the Western role-playing game market and establish the company's Megami Tensei franchise through its Persona sub-series.

Persona, previously marketed as Shin Megami Tensei: Persona outside of Japan, is a video game franchise primarily developed and published by Atlus, and owned by Sega. Centered around a series of role-playing video games, Persona is a spin-off from Atlus' Megami Tensei franchise. The first entry in the series, Revelations: Persona, was released in 1996 for the PlayStation. The series has seen several more games since, with the most recent main entry being 2024's Persona 3 Reload.
