Marjorie "Marge" Simpson (née Bouvier) is a fictional main character in the animated television series The Simpsons and part of the eponymous family. She is voiced by actress Julie Kavner and first appeared on television in The Tracey Ullman Show short "Good Night" on April 19, 1987. Marge was created and designed by cartoonist Matt Groening while he was waiting in the lobby of James L. Brooks' office. Groening had been called to pitch a series of shorts based on Life in Hell but instead decided to create a new set of characters. He named the character after his mother Margaret Groening. After appearing on The Tracey Ullman Show for three seasons, the Simpson family received their own series on Fox, which debuted December 17, 1989.

Marge is the well-meaning and extremely patient mother of the Simpson family. With her husband Homer, she has three children: Bart, Lisa, and Maggie. Marge is the moralistic force in her family and often provides a grounding voice in the midst of her family's antics by trying to maintain order in the Simpson household. She is often portrayed as a stereotypical television mother and is often included on lists of top "TV moms". She has appeared in other media relating to The Simpsons—including video games, The Simpsons Movie, The Simpsons Ride, commercials, and comic books—and inspired an entire line of merchandise.

Marge's distinctive blue beehive hairstyle was inspired by a combination of The Bride of Frankenstein and the style that Margaret Groening wore in the 1960s. Julie Kavner, who was a member of the original cast of The Tracey Ullman Show, was asked to voice Marge so that more voice actors would not be needed. Kavner has won several awards for voicing Marge, including a Primetime Emmy Award for Outstanding Voice-Over Performance in 1992. She was also nominated for an Annie Award for Best Voice Acting in an Animated Feature for her performance in The Simpsons Movie. In 2000, Marge, along with the rest of her family, was awarded a star on the Hollywood Walk of Fame.
