The Operating System Embedded (mostly known under the acronym OSE) is a real-time embedded operating system created by the Swedish information technology company ENEA. Bengt Eliasson, who at the time was a consultant from ENEA with an assignment at Ericsson, wrote the basic parts of the kernel.

OSE uses signaling in the form of messages passed to and from processes in the system. Messages are stored in a queue attached to each process. A 'link handler' mechanism allows signals to be passed between processes on separate machines, over a variety of transports. The OSE signalling mechanism formed the basis of an open-source inter-process communication project called LINX .

The system exists in several revisions named OSE for ARM processors, PowerPC and MIPS, OSE_ck for various DSP's and OSE Epsilon for minimal devices.
