RT-Thread is an open-source real-time operating system (RTOS) for embedded systems and Internet of things (IoT).{{cite web |url=https://www.rt-thread.io |title=RT-Thread 启动下一代RTOS演化}}{{cite web |url=https://github.com/RT-Thread/rt-thread |title=RT-Thread github|website=GitHub |date=23 October 2022 }} It is developed by the RT-Thread Development Team based in China. RT-Thread is aimed to change the current situation in China that there is no well used open-source real-time operating system in the microcontroller field.

{{As of|2020|08}}, RT-Thread was reported to be #3 on the list of RTOSes with the largest number of contributors (behind Zephyr and Mbed).{{Cite web |url=https://youtube.com/watch?v=jR5E5Kz9A-k |title=Introduction to the Zephyr RTOS |publisher=Nordic Semiconductor |date=October 6, 2020}}
