The YF-100 is a Chinese liquid rocket engine burning LOX and kerosene in an oxidizer-rich staged combustion cycle. The engine is designed for use on the first stage of the Chinese government's new generation of launch vehicles, the Long March 5, the Long March 6 and the Long March 7. The engine's maiden flight, on the Long March 6, took place on September 20, 2015.

Development of the engine began in the 2000s, along with its sibling, the smaller YF-115, which would power the upper stages of the Long March 6 and Long March 7 rockets. Testing was directed by the China National Space Administration (CNSA) commencing in 2005. Development works are mainly carried out by the Xi'an Aerospace Propulsion Institute. The engine had its first 300 seconds test fire in November 2007.
