After Dark is a series of computer screensaver software introduced by Berkeley Systems in 1989 for the Apple Macintosh, and in 1991 for Microsoft Windows.

[4] On top of the included animated screensavers, the program allowed for the development and use of third-party modules, many hundreds of which were created at the height of its popularity.

[9] The case was dismissed because the cover art had not been registered as a trademark by the group prior to Berkeley Systems' release of the screensaver.

[12] For Apple silicon and Intel Macs, remakes of three popular modules — Flying Toasters, Mowing Man and Boris — are being sold as standalone screensavers.
