HarmonyOS NEXT (Chinese: 鸿蒙星河版; pinyin: Hóngméng Xīnghébǎn) is a proprietary distributed operating system and an iteration of HarmonyOS, developed by Huawei to support only HarmonyOS native apps. The operating system is primarily aimed at software and hardware developers that deal directly with Huawei. It does not include Android's AOSP core and is incompatible with Android applications.

While on the one hand discarding the common Unix-like Linux kernel, the NEXT version also replaces the old HarmonyOS multikernel and is built on a custom version of OpenHarmony. The HarmonyOS microkernel is placed at its core with a single framework; also included is the LiteOS operating system for resource-constrained devices like wearables and IoT products.

The first internal preview version of the system was revealed on August 4, 2023, and the first preview version was released to registered public developers on January 18, 2024.

The devices tested on the developer preview version of the system were the Mate 60, Mate 60 Pro, and Mate X5 phones in the first batch.
