HarmonyOS Kernel (HongMeng Kernel), sometimes referred to as the Harmony kernel, is a computer operating system (OS) kernel developed by Huawei since August 2023. It is used in the HarmonyOS NEXT version of the proprietary HarmonyOS operating system, replacing previous versions that utilized the AOSP compatibility layer, the Linux kernel, and the LiteOS kernel.^[1][2]

The HarmonyOS Kernel utilizes a microkernel architecture, which aims to improve security and performance by isolating critical components of the system.
