What religion is Nancy Cartwright?
Nancy Cartwright’s involvement in Scientology
- Cartwright has been a practicing member of the Church of Scientology since the early 1990s. According to The Independent (UK news outlet), she converted in 1991.
- Multiple outlets have covered her faith publicly for over a decade, including The Hollywood Reporter (entertainment trade journal), which reported in 2009 that she recorded a message for Scientology using her Bart Simpson voice.
Cartwright’s use of a globally recognized character voice for a religious message blurred the line between entertainment and advocacy — a move that generated ongoing press interest and raised questions about intellectual property.
How Scientology affects her personal life
- Cartwright has defended Scientology in interviews. The Independent noted in 2023 that she “has publicly defended the church against criticism.”
- A conflicting claim from Tuko.co.ke (Kenyan news aggregator) lists her religion as Christianity, but this source is low-confidence and contradicts all other major reporting.
Do Scientologists have restrictions on friendships?
Scientology encourages members to socialize both within and outside the church, though some former members have described pressure to limit association with non-Scientologists. Cartwright has not publicly addressed this specific point, but her long-standing friendships with co-stars on The Simpsons (many of whom are not Scientologists) suggest she maintains a wide circle.
Despite her high profile, Cartwright has rarely given deep interviews about how her faith interacts with her daily work — a silence that leaves room for speculation.
What is the net worth of Nancy Cartwright?
Nancy Cartwright’s earnings from The Simpsons
- Cartwright earns approximately $300,000 per episode of The Simpsons, according to Reality Tea (celebrity news site).
- With over 750 episodes aired, that adds up to a substantial base income over nearly four decades.
Other income sources: voice acting, producing, books
- Beyond The Simpsons, Cartwright voiced Chuckie Finster in Rugrats and appeared in The Critic and other shows.
- She wrote a memoir, My Life as a 10-Year-Old Boy (2000), and launched the podcast Simpsons Declassified in 2018.
Net worth estimates and comparisons
Estimates vary. Reality Tea reports $55 million as of 2025; Backstage (performer resource platform) places her at approximately $60 million and ranks her among the highest-paid voice actors. TVOvermind (entertainment blog) gives a higher figure of $80 million. The discrepancy is typical of celebrity net worth reporting, where different methodologies produce different numbers.
How many Simpsons voices does Nancy Cartwright do?
List of characters voiced by Nancy Cartwright
- Cartwright voices over 100 distinct characters on The Simpsons, according to Wikipedia.
- Her most famous roles include Bart Simpson, Ralph Wiggum, Nelson Muntz, Todd Flanders, and Kearney Zzyzwicz.
The process of voicing multiple characters
In recording sessions, Cartwright shifts between characters by adjusting pitch, cadence, and attitude — often within the same line read. She has described in interviews how Bart’s voice came from a lower register than her natural speaking voice, while Ralph requires a slower, more nasal delivery.
Records and achievements
Cartwright won the Primetime Emmy Award for Outstanding Voice-Over Performance in 1992 for her work as Bart Simpson. She remains the only female voice actor on The Simpsons to hold a Primetime Emmy for voice work.
Is Sabrina Carpenter related to Nancy Cartwright?
Sabrina Carpenter’s family tree

Nancy Cartwright’s family: husband, children
- Cartwright was married to Warren Murphy (producer) from 1988 to 2002. They have two children: a son, Joshua, and a daughter, Jackson.
How the rumor started
The confusion likely stems from the shared “Cartwright” surname and the fact that both women are in the entertainment industry. No credible source links them as relatives. Cartwright has never mentioned a connection, and Carpenter has not claimed one.
Internet rumors about celebrity families spread fast. For readers: always check multiple reliable sources before assuming a family tie.
