Jean Rhys, CBE (born Ella Gwendolyn Rees Williams; 24 August 1890–14 May 1979) was a British novelist who was born and grew up in the Caribbean island of Dominica. From the age of 16, she mainly resided in England, where she was sent for her education. She is best known for her novel Wide Sargasso Sea (1966), written as a prequel to Charlotte Brontë's Jane Eyre.

She moved to England at the age of 16 years in 1906 and worked unsuccessfully as a chorus girl. In the 1920s, she relocated to Europe, travelled as a Bohemian artist, and took up residence sporadically in Paris. During this period, Rhys, familiar with modern art and literature, lived near poverty and acquired the alcoholism that persisted throughout the rest of her life. Her experience of a patriarchal society and displacement during this period formed some of the most important themes in her work.
