This list of GNU packages lists notable software packages developed for or maintained by the Free Software Foundation as part of the GNU project, a Unix-like computer operating system composed entirely of free software. Many of these software packages are used together with the Linux kernel to build complete computer operating systems.
What it means to be a GNU package 
Summarising the situation in 2013, Richard Stallman identified nine aspects which generally apply to being a GNU package, but he noted that exceptions and flexibility are possible when there are good reasons:
- The package should say that it is a GNU package
- It should be distributed via ftp.gnu.org, or another site offering access to everyone
- The package's homepage should be on the GNU website
- The developers must pay attention to making their software work well with other GNU packages
- Documentation should be in Texinfo format, or in a format easily convertible to Texinfo
- Should use GNU Guile for its extension language, but exceptions are explicitly possible in this regard
- Should not recommend any non-free program, nor refer the user to any non-free documentation or non-free software
- Use GNU terminology, such as GNU/Linux for the operating system and "free software" rather than "open source"
- The maintainer should be contactable, at least infrequently, to discuss problems in the software or fixing compatibility issues
Base system 
There is no official "base system" of the GNU operating system. GNU was designed to be a replacement for Unix operating systems of the 1980s and used the POSIX standards as a guide, but either definition would give a much larger "base system". The following list is instead a small set of GNU packages which seem closer to being "core" packages than being in any of the further down sections. Inclusions (such as plotutils) and exclusions (such as the C standard library) are of course debatable.

- Stable versions. Note that some distros (e.g., Gentoo) use some development versions in case the stable versions are a bit old.
- Note that because GRUB is unstable, there is no stable version, although many distros use it as default.
- Note that because HURD is under active development, there is no stable version. Hurd is distributed through version control systems.
