Software Freedom Conservancy, Inc. (also known as "Conservancy") is an American non-profit organization that provides infrastructure and legal support for free and open-source software projects. The organization was established in 2006, and as of June 2022, had over 40 member projects.

In 2007, Conservancy started coordinating GNU General Public License compliance and enforcement actions, primarily for the BusyBox project.

In October 2010, Conservancy hired its first executive director, Bradley M. Kuhn and a year later, its first General Counsel, Tony Sebro. In May 2012, Conservancy took on GPL compliance and enforcement for several other member projects, as well as for a number of individual Linux kernel developers. In March 2014, Conservancy appointed Karen Sandler as its executive director, with Bradley M. Kuhn taking on the role as Distinguished Technologist.

In February 2015, the Outreachy program (formerly the Free and Open Source Software Program for Women) announced that it was moving from The GNOME Project to become part of Conservancy.

By July 2015, Conservancy had reached 30 member projects, including QEMU, Boost, BusyBox, Git, Inkscape, Samba, Sugar Labs and Wine.

In May 2016, Yorba Foundation assigned the copyrights of the projects it developed to Conservancy, including Shotwell, Geary, Valencia, and gexiv2.

In November 2017, Conservancy reported that the Software Freedom Law Center had demanded the invalidation of the SFC's trademark.^{[non-primary source needed]}

In June 2022, in reaction to the GitHub Copilot licensing controversy, Conservancy introduced their "Give Up GitHub" campaign. The campaign urged open source developers to move away from GitHub to Codeberg or SourceHut, or to self-hosted platforms.
