Mary Kay Bergman (June 5, 1961–1999) was an American voice actress celebrated for her versatility and the breadth of characters she created in late-20th-century animation. She is widely remembered for providing the majority of the female voices on the adult animated sitcom South Park, and for early work on other cartoons that reached large young and adult audiences, including an initial portrayal of Timmy Turner associated with The Fairly OddParents. Her performances combined comedic timing, quick character switches and a broad vocal range.

Career and notable roles

Bergman’s career encompassed television, film and video-game voice work. She was frequently cast to voice multiple distinct characters in a single production, a skill valued in ensemble animation. Notable credits and recurring associations include:

  • Most female characters on South Park, including many adult and child roles.
  • Early or pilot voice work tied to projects such as The Fairly OddParents.
  • Guest and supporting parts across television animation and video games, demonstrating a flexible timbral range.

Colleagues in the field, including performers from long-running animated series such as The Simpsons, remember her for both her professional skill and collaborative spirit. She maintained friendships with peers like Nancy Cartwright and Grey DeLisle, who went on to build prominent voice careers of their own.

Style and technique

Bergman’s technique blended characterization—distinct accents, pitches and affect—with the kind of rapid switching needed when one actor voiced many roles during a session. This made her especially valuable on series that relied on a small cast to populate a varied fictional world. Her background included voice training and performance experience that informed a naturalistic yet expressive approach to animated comedy and dramatic moments alike.

Personal life, health and death

Off stage she was married to fellow voice actor Dino Andrade. Bergman privately struggled with mental-health conditions later publicly described by friends and family, including bipolar disorder and generalized anxiety disorder. In 1999 she died by suicide; reports note she took her own life following a period of untreated or undertreated illness. Her last public appearance was at an event celebrating Disneyland’s anniversary earlier that day.

Legacy and recognition

Mary Kay Bergman’s work is cited by animators and voice actors as an example of how one performer can shape the tone and personality of a series through multiple roles. After her death, several productions re-cast or redistributed characters she had performed, and tributes from peers highlighted both her technical gifts and the need for greater mental-health awareness in the entertainment community. Her career continues to be discussed in histories of modern animation and in conversations about performer attribution and ensemble casting.
