In 1989, Epic Comics published a 48-page graphic novel version by Tom de Haven and Bruce Jensen. It only covers the first two chapters, "Chiba City Blues" and "The Shopping Expedition," and was never continued.
In the 1990s a version of Neuromancer was published as one of the Voyager Company's Expanded Books series of hypertext-annotated HyperCard stacks for the Apple Macintosh (specifically the PowerBook).
A video game adaptation of the novel – also titled Neuromancer — was published in 1988 by Interplay. Designed by Bruce J. Balfour, Brian Fargo, Troy A. Miles, and Michael A. Stackpole, the game had many of the same locations and themes as the novel, but a different protagonist and plot. It was available for a variety of platforms, including the Amiga, the Apple II, the Commodore 64, and for DOS-based computers. It featured, as a soundtrack, a computer adaptation of the Devo song "Some Things Never Change."
According to an episode of the American version of Beyond 2000, the original plans for the game included a dynamic soundtrack composed by Devo and a real-time 3d rendered movie of the events the player went through. Psychologist and futurist Dr. Timothy Leary was involved, but very little documentation seems to exist about this proposed second game, which was perhaps too grand a vision for 1988 home computing.
The BBC World Service Drama production of Neuromancer aired in two one-hour parts, on 8 and 15 September 2002. Dramatised by Mike Walker, and directed by Andy Jordan, it starred Owen McCarthy as 'Case', Nicola Walker as 'Molly', James Laurenson as 'Armitage', John Shrapnel as 'Wintermute', Colin Stinton as 'Dixie', David Webber as 'Maelcum', David Holt as 'Riviera', Peter Marinker as 'Ashpool', and Andrew Scott as 'The Finn'. It can no longer be heard on The BBC World Service Archive. 
Gibson read an abridged version of his novel Neuromancer on four audio cassettes for Time Warner Audio Books (1994). An unabridged version of this book was read by Arthur Addison and made available from Books on Tape (1997). In 2011, Penguin Audiobooks produced a new unabridged recording of the book, read by Robertson Dean.
Neuromancer the Opera is an adaptation written by Jayne Wenger and Marc Lowenstein (libretto) and Richard Marriott of the Club Foot Orchestra (music). A production was scheduled to open on March 3, 1995 at the Julia Morgan Theater (now the Julia Morgan Center for the Arts) in Berkeley, California, featuring Club Foot Orchestra in the pit and extensive computer graphics imagery created by a world-wide network of volunteers. Unfortunately this premiere did not take place and the work has yet to be performed in full.
There have been several proposed film adaptations of Neuromancer, with drafts of scripts written by British director Chris Cunningham and Chuck Russell. The box packaging for the video game adaptation had even carried the promotional mention for a major motion picture to come from "Cabana Boy Productions." None of these projects have come to fruition, though Gibson had stated his belief that Cunningham is the only director with a chance of doing the film correctly.
In May 2007 reports emerged that a film was in the works, with Joseph Kahn (director of Torque) in line to direct and Milla Jovovich in the lead role. In May 2010 this story was supplanted with news that Vincenzo Natali, director of Cube and Splice, had taken over directing duties and would rewrite the screenplay. In March 2011, with the news that Seven Arts and GFM Films would be merging their distribution operations, it was announced that the joint venture would be purchasing the rights to Neuromancer under Vincenzo Natali's direction. In August, 2012, GFM Films announced that it had begun casting for the film (with offers made to Liam Neeson and Mark Wahlberg), but no cast members have been confirmed yet. In November 2013, Natali shed some light on the production situation; announcing that the script had been completed for 'years', and had been written with assistance from Gibson himself.
