OpenMandriva Lx is a general-purpose Linux distribution maintained by the OpenMandriva Association for x86_64 (64-bit) and ARM computers. It is a community-supported continuation of Mandriva Linux, which was active from 1998 (as Mandrake) until 2011. OpenMandriva is offered in a stable release edition, and (since 2023) a rolling release edition named Rome. It uses the RPM Package Manager and uses KDE Plasma as its default desktop environment.

OpenMandriva Lx's development environment is an ABF (Automated Build Farm) which can manage the source code and compile it to binaries. ABF also creates the package repository and ISO images.

OpenMandriva Lx is a community Linux distribution. Originally an offering of Mandriva Linux, the OpenMandriva product was created in May, 2012, when Mandriva S.A. avoided bankruptcy by abandoning the development of its consumer product to the Mandriva community.

The OpenMandriva Association was established on December 12, 2012, under 1901 French law, to represent the OpenMandriva Community.
