Fay Weldon (born Franklin Birkinshaw; 22 September 1931 – 4 January 2023) was an English author, essayist and playwright.

Over the course of her 55-year writing career, she published 31 novels, including Puffball (1980), The Cloning of Joanna May (1989), Wicked Women (1995) and The Bulgari Connection (2000), but was most well-known as the writer of The Life and Loves of a She-Devil (1983) which was televised by the BBC in 1986.

Married three times and with four children, Weldon was a self-declared feminist. Her work features what she described as "overweight, plain women". She said there were many reasons why she became a feminist, including the "appalling" lack of equal opportunities and the myth that women were supported by male relatives.
