The Tianlong-2 ({{zh|s=天龙二号|t=天龍二號|p=Tiānlóng Èrhào|l=Heavenly Dragon 2}}) is a small-lift launch vehicle developed by Space Pioneer, a private Chinese aerospace company. The rocket is a three-stage design that uses liquid oxygen and kerosene as its main propellants. Its initial low-Earth orbit capacity is 2 tons, which can be increased to 4 tons after future improvements.

Tianlong-2 successfully completed its maiden flight on April 2, 2023. It is China's first liquid rocket developed by a private enterprise and successfully put into orbit.
