'''MirOS BSD''' (originally called '''MirBSD''') is a [[free and open source software|free and open source]] [[operating system]] which started as a fork of [[OpenBSD]] 3.1 in August 2002.<ref name="origins">[https://www.mirbsd.org/permalinks/wlog-10_e20100828-tg.htm#e20100828-tg_wlog-10 Birthing point for MirOS]</ref> It was intended to maintain the security of OpenBSD with better support for European localisation. Since then it has also incorporated code from other free BSD descendants, including [[NetBSD]], MicroBSD (owned by DamnSmallBSD<ref>https://damnsmallbsd.org/MicroBSD/</ref>) and [[FreeBSD]]. Code from MirOS BSD was also incorporated into ekkoBSD, and when ekkoBSD ceased to exist, artwork, code and developers ended up working on MirOS BSD for a while.

Unlike the [[Comparison of BSD operating systems#Technical information|three major BSD distributions]], MirOS BSD supports only the [[x86]] and SPARC architectures.

One of the project's goals was to be able to port the MirOS userland to run on the [[Linux]] kernel, hence the deprecation of the MirBSD name in favour of MirOS.
