Fuxing (simplified Chinese: 复兴号; traditional Chinese: 復興號; pinyin: Fùxīng Hào ; lit. 'Rejuvenation') (also known as the CR series EMU, or as the Fuxing Hao ) is a series of high-speed and higher-speed EMU trains operated by China Railway High-speed (CRH) and developed by CRRC, which owns the independent intellectual property rights entirely. The Fuxing series do not contain any technology that is patented or licensed by foreign train makers, and demonstrates China's ability to build faster trains through homegrown innovations.

Initially known as the China Standardized EMU , development on the project started in 2012, and the design plan was finished in September 2014. The first EMU rolled off the production line on 30 June 2015. The series received its current designation of Fuxing in June 2017, with nicknames such as " Blue/Red Dolphin " (CR400AF) and " Golden Phoenix " (CR400BF) for certain units. It is among the world's fastest conventional high speed trains in regular service, with an operating speed of 350 km/h (220 mph) for the CR400AF and CR400BF models.

The export version of the train sets also operate in Indonesia on the Jakarta- Bandung high-speed railway from 2023, with a derivative version of CR400AF, also known as KCIC400AF or " Komodo Merah " (literally: red komodo dragon) or " Petir Merah " (literally: red lightning). The CR450 will be the latest model in the Fuxing series and is designed to have a maximum operating speed of 400 km/h, and expected to enter service by 2025. In 2023, a CR450 train had attained speeds of 453 km/h (281 mph) during a test run, accompanied with velocity speeds of 891 km/h (553 mph).
