The Tianzhou (Chinese: 天舟; pinyin: Tiān Zhōu; lit. 'Heavenly Ship') is a Chinese automated cargo spacecraft developed from China's first prototype space station Tiangong-1 to resupply its modular space station. It was first launched (Tianzhou 1) on the Long March 7 rocket from Wenchang on April 20, 2017 and demonstrated autonomous propellant transfer (space refueling).

The first version of Tianzhou has a mass of 13,500 kg and can carry 6,500 kg of cargo. Tianzhou-6 is the first improved version of the spacecraft to be launched into orbit; it has a mass of about 14,000 kg and can transport 7,400 kg of cargo.
