There have been three film adaptations based on the book:
- Lord of the Flies (1963), directed by Peter Brook
- Alkitrang Dugo (1975), a Filipino film, directed by Lupita A. Concio
- Lord of the Flies (1990), directed by Harry Hook
A fourth adaptation, to feature an all-female cast, was announced by Warner Bros. in August 2017, but was subsequently abandoned. In July 2019, director Luca Guadagnino was said to be in negotiations for a conventionally cast version. Ladyworld, an all-female adaptation, was released in 2018.
Nigel Williams adapted the text for the stage. It was debuted by the Royal Shakespeare Company in July 1996. The Pilot Theatre Company has toured it extensively in the United Kingdom and elsewhere.
In October 2014 it was announced that the 2011 production of Lord of the Flies would return to conclude the 2015 season at the Regent's Park Open Air Theatre ahead of a major UK tour. The production was to be directed by the Artistic Director Timothy Sheader who won the 2014 Whatsonstage.com Awards Best Play Revival for To Kill a Mockingbird.
In June 2013, BBC Radio 4 Extra broadcast a dramatisation by Judith Adams in four 30-minute episodes directed by Sasha Yevtushenko. The cast included Ruth Wilson as "The Narrator", Finn Bennett as "Ralph", Richard Linnel as "Jack", Caspar Hilton-Hilley as "Piggy" and Jack Caine as "Simon".
