Ayana Inoue is a Japanese voice actor and actress born on April 30, 1967, in Tokyo, Japan. She is affiliated with the talent agency Media Force. Inoue is primarily recognized for her voice work in the unconventional anime and video game series Gregory Horror Show.

Her most prominent and defining role is providing the voice for the character Nurse Catherine in the Gregory Horror Show franchise. Nurse Catherine is a memorable and sinister character, a pink reptilian nurse with an obsessive and violent compulsion to draw blood from the hotel's guests using a large syringe. Inoue is credited as the first Japanese voice for this character in the original Gregory Horror Show television series and its sequel, Gregory Horror Show: The Second Guest. She also voiced the character in the 2003 PlayStation 2 video game adaptation, Gregory Horror Show: Soul Collector. Her portrayal contributed significantly to the character's eerie and darkly comedic presence, which became a fan favorite. In the later spin-off series centered on the character, The Bloody Karte, the role of Nurse Catherine was voiced by Minako Ichiki.

Beyond her iconic work in the Gregory Horror Show franchise, information about Inoue's other voice acting roles is limited. She is credited with a role as Penpe in the television series Guru Guru Town Hanamaru-kun. Her filmography also includes a role in the live-action movie Zero Woman: The Accused. In addition to acting, she has been credited as an author and provided 3D assistance for an episode of FLCL: Grunge. Due to the sparse nature of available information, a comprehensive profile of her career, including recurring collaborations with specific directors or a wider range of major voice roles, cannot be constructed.
