GNU Bazaar (formerly Bazaar-NG, command line tool bzr) is a distributed and client–server revision control system sponsored by Canonical.

Bazaar can be used by a single developer working on multiple branches of local content, or by teams collaborating across a network.

Bazaar is written in the Python programming language, with packages for major Linux distributions, {{nowrap|Mac OS X}} and Microsoft Windows. Bazaar is free software and in 2008 became part of the GNU Project.{{cite mailing list
