The TianQin Project () is a proposed space-borne gravitational-wave observatory (gravitational-wave detector) consisting of three spacecraft in Earth orbit. The TianQin project is being led by Professor Luo Jun (), President of Sun Yat-sen University, and is based in the university's Zhuhai campus. Construction on project-related infrastructure, which will include a research building, ultra-quiet cave laboratory, and observation center, began in March 2016. The project is estimated to cost 15 billion RMB (US$2.3 billion), with a projected completion date in the mid-2030s. In December 2019, Chi
The TianQin Project () is a proposed space-borne gravitational-wave observatory (gravitational-wave detector) consisting of three spacecraft in Earth orbit. The TianQin project is being led by Professor Luo Jun (), President of Sun Yat-sen University, and is based in the university's Zhuhai campus.

The project is estimated to cost 15 billion RMB (US$2.3 billion), with a projected completion date in the mid-2030s. In December 2019, China launched Tianqin-1, a technology demonstration.
The project's name combines the Chinese words "Tian", meaning heavenly or celestial, and "Qin", a type of traditional instrument in Chinese musical culture. This name refers to the metaphorical concept of gravitational waves "plucking the strings" by causing fluctuations in the 100,000 kilometer laser beams stretching between each of the three TianQin spacecraft.
