The GNU Hackers' Meeting is a more or less annual event where developments in the GNU operating system are discussed and ideas exchanged. Unlike some larger events it has a friendly and welcoming atmosphere, and aims to make all participants feel at home.

The meeting is a semi-formal meeting usually spanning three days and is open to all people interested in the GNU operating system. Typically, the format includes talks, seminars and discussions, as well as a chance for social interaction with maintainers, users and developers of GNU software.
