GNOME () is a free and open-source desktop environment for Unix-like operating systems. GNOME was originally an acronym for GNU Network Object Model Environment, but the acronym was dropped because it no longer reflected the vision of the GNOME project.

GNOME is developed by The GNOME Project, which is composed of both volunteers and paid contributors, the largest corporate contributor being Red Hat. It is an international project that aims to develop software frameworks for the development of software, to program end-user applications based on these frameworks, and to coordinate efforts for internationalization and localization and accessibility of that software.

GNOME 3 is the default desktop environment on many major Linux distributions including Fedora, Debian, Ubuntu, SUSE Linux Enterprise, Red Hat Enterprise Linux, CentOS, Pop!_OS, Oracle Linux, Endless OS, and Tails; as well as Solaris, a Unix operating system. The continued fork of the last GNOME 2 release, called MATE, is default on many Linux distros that target low usage of system resources.
