Agnes Moorehead (18 November 1948). Joan Fontaine and Joseph Cotten performed a half-hour adaptation 1 October 1946 on The Cresta Blanca Hollywood Players. The Lux Radio Theatre presented hour-long adaptations with Ronald Colman, Ida Lupino and Judith Anderson (3 February 1941), and with Laurence Olivier, Vivien Leigh and Betty Blythe (6 November 1950). These were tie-ins to the Hitchcock film, and perpetuated the censorship of the novel which the Hays Office had imposed on that film, although Orson Welles' radio version which predated the film (and including a promotion for the film) was faithful to the original, asserting that Max de Winter had deliberately murdered Rebecca. Theatre Du Maurier herself adapted Rebecca as a stage play in 1939; it had a successful London run in 1940 of over 350 performances.

A Broadway stage adaptation starring Diana Barrymore, Bramwell Fletcher and Florence Reed ran 18 January – 3 February 1945, at the Ethel Barrymore Theatre. The book has also been adapted into a German-language musical, Rebecca, which opened in Vienna in 2006 and ran for three years. Opera Rebecca was adapted as an opera with music by Wilfred Josephs, premiered by Opera North in Leeds, England, 15 October 1983. Sequels and related works The novel has inspired three additional books approved by the du Maurier estate: Mrs de Winter (1993) by Susan Hill. () The Other Rebecca (1996) by Maureen Freely. () Rebecca's Tale (2001) by Sally Beauman () In addition, a number of fan fiction websites feature sequels, prequels, and adaptations of this novel.

Sentences would be made using single words in the book, referred to by page number, line and position in the line. One copy was kept at Rommel's headquarters, and the other was carried by German Abwehr agents infiltrated into Cairo after crossing Egypt by car, guided by Count László Almásy. This code never was used, however, because the radio section of the headquarters was captured in a skirmish and hence the Germans suspected that the code was compromised. This use of the book
