Qiaowanlong is a genus of sauropod dinosaur from the Albian stage of the Early Cretaceous Period (100 million years ago). It was discovered in the Yujinzi Basin of Gansu, China in 2007. It came from the geological formation called the Xinminpu Group.

Qiaowanlong is known from articulated cervical (neck) vertebrae and a right pelvic girdle, as well as several unidentified bone fragments. It was the first brachiosaurid to have been found from China.

Qiaowanlong is estimated to have been about 40 feet long and weigh about 11 tons.

Qiaowanlong is thought to be closely related to Sauroposeidon, a North American genus. The type species is Q. kangxii.
