Quod Libet is a cross-platform free and open-source audio player, tag editor and library organizer. The main design philosophy is that the user knows how they want to organize their music best; the software is therefore built to be fully customizable and extensible using regular expressions and boolean logic. Quod Libet is based on GTK and written in Python, and uses the Mutagen tagging library.

Quod Libet is very scalable, able to handle libraries with tens of thousands of songs. It provides a full feature set including support for Unicode, regular expression searching, key bindings to multimedia keys, fast but powerful tag editing, and a variety of plugins.

Quod Libet is available on most Linux distributions, macOS and Windows, requiring only PyGObject, Python, and an Open Sound System (OSS), ALSA or JACK compatible audio device. The XFCE desktop ISO image provided by the Debian project installs Quod Libet as the default audio player.{{Cite web |url=https://cdimage.debian.org/debian-cd/current-live/i386/iso-hybrid/debian-live-9.5.0-i386-xfce.packages |title=Archived copy |access-date=5 October 2018 |archive-date=5 October 2018 |archive-url=https://web.archive.org/web/20181005194858/https://cdimage.debian.org/debian-cd/current-live/i386/iso-hybrid/debian-live-9.5.0-i386-xfce.packages |url-status=dead }}

Quod Libet's tag-editing and library organization features are also available through a standalone program, Ex Falso, which is based on the same code and libraries as Quod Libet.
