Huanghetitan (meaning "Yellow River titan"), is a genus of sauropod dinosaur from the early Cretaceous Period.

It is known from fragmentary materials including two caudal vertebrae, an almost complete sacrum, rib fragments, and the left shoulder girdle, and was discovered in the eastern part of the Lanzhou Basin (Hekou Group) in the Gansu Province in 2004.

A recent cladistic analysis has found that this species is unlikely to be closely related to H. liujiaxiaensis and requires a new genus name.

[3] H. ruyangensis is known from a partial vertebral column and several ribs, the size of which (the largest approaches 3 m (10 ft)) indicate it had among the deepest body cavities of any known dinosaur.

[4] This second species, along with its local relatives Daxiatitan and Ruyangosaurus, is one of the biggest dinosaurs ever found in Asia, and possibly one of the largest in the world.
