Marjorie Gross (April 18, 1956 – June 7, 1996) was a Canadian television writer and producer. In addition to writing for Seinfeld, she also wrote for Newhart, The Larry Sanders Show and Square Pegs.

She wrote the following episodes:

Season Six

Season Seven

Marjorie passed away due to ovarian cancer in June 1996; she was 40 years young. Early in 1996 she wrote an article, "Cancer Becomes Me," for The New Yorker. She tried to find humor in the situation by joking that she wanted to hold on until November 1996, so that she would not have to risk being re-incarnated as Madonna's child. (Madonna was pregnant and expecting.)

The season eight premiere, "The Foundation", was dedicated in her memory.
