Forever Amber (1944) is an historical romance novel by Kathleen Winsor set in 17th-century England. It was made into a film in 1947 by 20th Century Fox.

Kathleen Winsor was an American author. She is best known for her first work, the 1944 historical novel Forever Amber. The novel, racy for its time, became a runaway bestseller even as it drew criticism from some authorities for its depictions of sexuality. She wrote seven other novels, none of which matched the success of her debut.
