Philippa Gregory is an English historical novelist who has been publishing since 1987. The best known of her works is The Other Boleyn Girl (2001), which in 2002 won the Romantic Novel of the Year Award from the Romantic Novelists' Association and has been adapted into two films.

The Other Boleyn Girl (2001) is a historical novel written by British author Philippa Gregory, loosely based on the life of 16th-century aristocrat Mary Boleyn of whom little is known. Inspired by Mary's life story, Gregory depicts the annulment of one of the most significant royal marriages in English history and conveys the urgency of the need for a male heir to the throne. Much of the history is highly distorted in her account.
