μT-Kernel is an open source real-time operating system (RTOS) designed for 16- and 8-bit microcontrollers. "μ” in the name stands for "micro" and pronounced as such. It is not pronounced as "mu". It is freely available under T-License.

Supported CPU list is available.{{Cite web |title=Supported CPU list |url=https://www.tron.org/tron-project/what-is-t-kernel/hwinfo/ |access-date=2024-10-15 |website=www.tron.org |language=en-US}}

The latest version, μT-Kernel 3.0, is available from Github.{{Citation |last=TRON Forum |title=μT-Kernel 3.0 distribution - tron-forum/mtkernel_3 |date=2024-10-02 |url=https://github.com/tron-forum/mtkernel_3 |access-date=2024-10-15}}

μT-Kernel was standardized by T-Engine Forum (now merged into TRON Forum{{Cite web |date=2024-05-10 |title=TRON Forum |url=https://www.tron.org/ |access-date=2024-10-15 |website=www.tron.org |language=en-US}}) and later it became the basis of IEEE Standard 2050-2018, "IEEE Standard for a Real-Time Operating System (RTOS) for Small-Scale Embedded Systems" {{Cite web |title=IEEE 2050-2018, IEEE Standard for a Real-Time Operating System (RTOS) for Small-Scale Embedded Systems |url=https://standards.ieee.org/ieee/2050/7178/ |access-date=2024-10-15 |website=IEEE Standards Association |language=en}} published by the Institute of Electrical and Electronics Engineers (IEEE) Standards Association (IEEE SA).

Its specification is available both in English and Japanese. [https://www.tron.org/specifications/] The source code is available from the TRON Forum website and GitHub.

An article comparing nine RTOSs in which μT-Kernel was evaluated and given favorable remarks appeared in IEEE publication.{{cite book |last=Su-Lim Tan; Tran Nguyen Bao Anh |chapter=Real-time operating system (RTOS) for small (16-bit) microcontroller |pages=1007–1011 |year=2009 |title=2009 IEEE 13th International Symposium on Consumer Electronics |publisher=IEEE Consumer Electronics Society |doi=10.1109/ISCE.2009.5156833 |isbn=978-1-4244-2975-2 |s2cid=27374625}}
