LineageOS also known as LineageOS Android Distribution and Lineage (/ˈlinēij/) is a free and open-source operating system for smartphones and tablet computers, based on the Android mobile platform. It is the successor to the highly popular custom ROM CyanogenMod, from which it was forked in December 2016 when Cyanogen Inc. announced it was discontinuing development and shut down the infrastructure behind the project. LineageOS was officially launched on December 24, 2016, with the source code available on GitHub.

Since Cyanogen Inc. retained the rights to the Cyanogen name, the project rebranded its fork as LineageOS.

CyanogenMod (often abbreviated "CM") was a highly popularopen-source operating system for smartphones and tablet computers, based on the Android mobile platform. Although only a subset of total CyanogenMod users elected to report their use of the firmware, as of 23 March 2015, some reports indicated over 50 million people running CyanogenMod on their phones. It was also frequently used as a starting point by developers of other ROMs.

In 2013, the founder, Steve Kondik, obtained venture funding under the name Cyanogen Inc. to allow commercialization of the project. However, the company did not, in his view, capitalize on the project's success and in 2016 he either left, or was forced out as part of a corporate restructure which involved a change of CEO, closure of offices and projects, and cessation of services. The code itself, being both open source and popular, was quickly forked under the new name LineageOS and community efforts began to resume development as a community project.
