Albalophosaurus (meaning 'white crest lizard') is a genus of ceratopsian ornithischian dinosaur. It was described in 2009 from remains found in 1997 by Yoshinori Kobayashi from the Kuwajima Formation of central Japan, outcropping in Hakusan in the Ishikawa Prefecture.The holotype, SBEI 176, consists of cranial bones from an incomplete, disarticulated skull and left lower jaw thought to belong to a single individual. The type species is named A. yamaguchiorum.

The exact age of the strata from which the remains of Albalophosaurus have been found is not known because of the lack of marine beds containing index fossils, but the Kuwajima Formation is known to have formed during the Early Cretaceous, most likely after theBerriasian and before the Barremian based on the ages of underlying and overlying formations. More recent studies suggest that the age of the Kuwajima Formation is most likely Valanginian—Hauterivian, although the exact age is still uncertain.
