The Wenchang Space Launch Site located in Wenchang, Hainan, China, is a rocket launch site, one of the two spacecraft launch sites of Xichang Satellite Launch Center.

It is a former suborbital test center. It is China's fourth and southernmost space vehicle launch facility (spaceport). It has been specially selected for its low latitude, which is only 19° north of the equator, which will allow for an increase in payload necessary for launching China's future space station. It is capable of launching the Long March 5, currently the most powerful Chinese rocket.
