Brigitta Dau is a Canadian actress recognized for her early work in anime voice acting, primarily known for providing the English voice for the female form of the protagonist in the Ranma ½ franchise. Her career in animation, though brief, is notable for being part of the original English dub production of this popular series.

Dau's most significant and widely recognized anime role is Ranma Saotome in his cursed girl-type form. She first voiced the character in the English dub of the Ranma ½ television series, starting with the first episode. Her tenure in the role was brief, covering only the initial six episodes of the show. Following these episodes, she departed from the series due to her relocation from Vancouver to Los Angeles, and the role was subsequently taken over by another actress. In addition to her work on the television series, Dau also voiced the girl-type Ranma in the Ranma ½ original video animation (OVA) releases.

Beyond her primary work on Ranma ½, information about other anime voice roles for Dau is extremely limited. Her career in the medium appears to have been concentrated on this single franchise during the early 1990s. She did, however, continue to work in voice acting for western animation, including a role in the children's series My Little Pony Tales.

Dau began her professional life as an actress in Vancouver, working in both live-action television and animation. After her move to Los Angeles in her early twenties, she transitioned away from acting to pursue other professional avenues. Her later career has included work as a speaker, author, and life coach.
