Betty Gustafson is a pseudonym used by the accomplished American voice actress Barbara Goodson for select roles in anime dubbing. Born on August 16, 1949, in Brooklyn, New York, Goodson has built an extensive career in voice-over work since the 1980s, contributing to numerous animated series, films, and video games. She is known for her remarkable vocal range, frequently voicing characters of different ages and genders, from young boys to elderly women.

The name Betty Gustafson appears in Goodson's early anime credits, most notably for her work in the Harmony Gold dub of the classic series Dragon Ball, where she provided the voice for the main character, Son Goku (referred to as Zero in this adaptation). This use of a pseudonym was not uncommon in the industry at the time, and Goodson has also been credited under other names, including Barbara Larsen, Bertha Greene, Jane Carole, and Janis Caroll. Her marriage to Bruce Gustafson is the origin of this particular professional alias.

Under the Betty Gustafson name, she contributed to several other anime productions that were dubbed for English-speaking audiences during the 1980s and 1990s. Her filmography includes roles in the fantasy series Serendipity Monogatari: Pyua-tou no Nakama-tachi, where she voiced multiple characters, including Bobby's Mother, the Narrator, and the titular role of Serendipity. She also voiced Princess Veronica in the animated feature Windaria, also known as Once Upon a Time. Additional credits from this period include roles in Maple Town, Noozles, and the Streamline Pictures dub of Lupin III: The Castle of Cagliostro.

Beyond the work done as Betty Gustafson, Barbara Goodson's career as a voice actor is marked by high-profile roles and industry recognition. She is widely recognized as the voice of the villainess Rita Repulsa in the long-running Power Rangers franchise, a role she has played for decades. Her other notable work includes Red Fraggle in Fraggle Rock, Naota Nandaba in the cult classic FLCL, Granny Chiyo in Naruto Shippuden, and Mother Talzin in Star Wars: The Clone Wars, a performance that earned her a Best Actress award from the website Behind The Voice Actors. For her narration of the audiobook On A Night Like This, she was awarded an Earphones Award from AudioFile magazine.
