Julie Kavner (born September 7, 1951) is an American actress, best known for her role as "Brenda Morgenstern" on the Rhoda television series in the 1970s and for providing the voice of "Marge Simpson" on the animated television show The Simpsons.

Kavner was born in Los Angeles, California and grew up entirely in Southern California, a fact that comes as a surprise to many people who identify her with her role as New Yorker Brenda Morgenstern and who peg her creaky, somewhat nasally voice as sounding "East Coast."
