Eight key facts about Nancy Cartwright, one pattern: her life is a blend of iconic voice work, a steadfast faith, and a tangled family tree.

Is Sabrina Carpenter related to Nancy Cartwright?

Yes, but the relationship is not biological. Nancy Cartwright publicly clarified in 2026 that Sabrina Carpenter is a relative, but not a biological niece. Cartwright explained that Sabrina’s father was her stepbrother because Sabrina’s grandmother married Cartwright’s father (Yahoo Entertainment (celebrity news)). In plain terms, Cartwright is Sabrina Carpenter’s step-grandmother.

How are they connected through family?

• Cartwright’s son married Sabrina Carpenter’s mother, creating a step-family bond (E! News)
• Cartwright first publicly confirmed the connection on TikTok in July 2024 (South China Morning Post)
• Sabrina Carpenter has called having Cartwright as an aunt the “coolest thing in the world” (SCMP)

The implication: the link is real but often misreported. Cartwright herself had to step in to clarify the exact nature of the relationship.

What is the biological relationship?

There is no direct biological relation. The two are connected through marriage: Cartwright’s son married Carpenter’s mother, making Cartwright a step-grandmother. Sabrina Carpenter’s father became Cartwright’s stepbrother through the marriage of his mother to Cartwright’s father (Yahoo Entertainment).

The takeaway: fans often confuse the degree of relation; the simplest label is “step-grandmother.”

How many Simpsons voices does Nancy Cartwright do?

Cartwright has voiced over 20 distinct characters on The Simpsons since the show premiered in 1989 (E! News). Her most iconic role is Bart Simpson, but she also voices Ralph Wiggum, Nelson Muntz, Todd Flanders, and several others.

• Ralph Wiggum — the sweet, dim-witted classmate
• Nelson Muntz — the school bully

How many total characters has she voiced on The Simpsons?

Over 20 distinct characters, according to multiple sources. The exact count fluctuates as new characters appear in episodes. She has been the show’s longest-serving voice actor alongside Dan Castellaneta (E! News).

Three net worth estimates, one pattern: the exact figure is impossible to pin down, but all agree she is a multi-millionaire.

Clarity: what we know and what we don’t

In their own words

“I knew Sabrina when she was a little girl. She’s always been so talented.”

— Nancy Cartwright, on her relationship with Sabrina Carpenter (Yahoo Entertainment)

“Having Nancy Cartwright as my aunt is the coolest thing in the world.”

— Sabrina Carpenter, in a 2021 interview with Capital FM (SCMP)

What these quotes reveal: the relationship is genuine and warm. Sabrina clearly admires Cartwright, and Cartwright has been a supportive presence in her life.

Summary

Nancy Cartwright has built a career few voice actors can match: 35 years as the voice of Bart Simpson, a Primetime Emmy, and a reported net worth of at least $55 million. Her faith in Scientology and her unexpected family link to Sabrina Carpenter add layers to a public persona that’s mostly known for a cartoon troublemaker. For fans of The Simpsons and pop culture trivia, the takeaway is clear: the woman behind Bart is far more complex than the character she voices.
