ArcaOS is a proprietary operating system based on OS/2, developed and marketed by Arca Noae, LLC under license from IBM. It was first released in 2017 and builds on OS/2 Warp 4.52 by adding support for new hardware, fixing defects and limitations in the operating system, and by including new applications and tools, and includes some Linux/Unix tool compatibility. It is targeted at professional users who need to run their OS/2 applications on new hardware, as well as personal users of OS/2.

Like OS/2 Warp, ArcaOS is a 32-bit single user, multiprocessing, preemptive multitasking operating system for the x86 architecture. It is supported on both physical hardware and virtual machine hypervisors.
