Catherine Disher is a British-born Canadian actress and voice artist with an extensive career in film, television, and animation. Born on June 22, 1960 in Paddington, England, she was raised in Montreal, Canada, and has become a prominent figure in the North American voice acting industry, recognized for her work across numerous animated series, video games, and feature films.

While Disher is widely known for her live-action roles, including Dr. Natalie Lambert on the television series Forever Knight and Mayor Martha Tinsdale on the Good Witch franchise, she has also contributed significantly to the field of anime dubbing. Her voice acting credits within the anime genre include the role of Myreille Psychiokieus in the series Beyblade: Metal Fusion. In the English-language dub of the animated feature Sailor Moon S: The Movie, she is credited as providing the voice of Princess Snow Kaguya, the main antagonist who seeks to encase the Earth in ice. This role appears in the film's original English dub produced in the late 1990s and early 2000s. It should be noted that while multiple sources attribute the role of Princess Snow Kaguya to Disher, other production records indicate that a different actress performed this character, leading to some uncertainty regarding the final casting of that specific film.

Beyond these specific anime projects, Disher's broader voice work demonstrates a deep involvement with animated storytelling. She is perhaps best known for originating the voice of Jean Grey, also known as the Phoenix, in the acclaimed 1990s X-Men: The Animated Series, a role she reprised decades later for the sequel series X-Men '97. Her career also includes extensive contributions to video game voiceovers, most famously as Jill Valentine in the survival horror classic Resident Evil 3: Nemesis, as well as voice roles in various installments of the Marvel vs. Capcom fighting game series. Her notable recurring collaboration includes working alongside actor Cedric Smith, who voiced Professor X on X-Men: The Animated Series; the two were formerly married.

Throughout her career, Disher has received several accolades for her live-action performances, including two Gemini Awards for her roles in the mini-series Snakes and Ladders and the television drama The Border. Her longevity in the entertainment industry is marked by a steady presence in both live-action and voice productions from the late 1980s to the present day, showcasing a versatility that spans children's animation, dramatic series, and feature film dubbing.
