Wide Sargasso Sea was adapted as a film in 1993 by Carol Angier, John Dugian, and Jan Sharpe. The Australian film stars Karina Lombard, Rachel Ward, Michael York, Nathaniel Parker, and Naomi Watts. The sexually explicit nature of the film earned it an NC-17 rating, but an edited Rrated version is also available through New Line Home Video.

The composer Gordon Crosse wrote a musical score called Memories of Morning: A Monodrama for Mezzo-soprano and Orchestra in 1973 that is loosely based on Rhys's novel. The score is available through Oxford University Press.

In 1996, Australian composer Brian Howard adapted Wide Sargasso Sea into a chamber opera.
