Probactrosaurus was an iguanodont hadrosauroid herbivorous hadrosauroid dinosaur that lived in the Late Cretaceous in present-day China. It was discovered by a Soviet-Chinese expedition in 1959 and 1960 in Inner Mongolia, near Moartu. The name means "before Bactrosaurus".

It was primarily a quadrupedal dinosaur, but may have been able to stand and walk on its hind legs alone for brief periods. It was a herbivorous dinosaur that fed on vegetation. It had relatively long, slender arms and hands and only a small beak on its thumb. Probactrosaurus had a slight build, a narrow snout, an elongated lower jaw and a tooth battery consisting of a double overlapping row of flattened cheek teeth. The third row of replacement teeth was incipient.

According to the scientist, Probactrosaurus shared some common features with later duck-billed dinosaurs.

It is estimated that Probactrosaurus was 5.5 meters long and weighed one ton.
