Tanius (meaning “of Tan”) is a genus belonging to hadrosauroid dinosaurs. It lived during the Late Cretaceous of China. The type species, which was named and identified in 1929 , by Carl Wiman, is Tanius sinensis. The name is a reference to Tan Xichou, the Chinese paleontologist Tan Xichou (“H.C. Tan”). The particular epithet is a reference to China. In 2010, Gregory S. Paul estimated the length of Tanius at seven meters and the weight was two tonnes.

Tan who was born in 1923 found the remains in the eastern part of Shandong in Ch’ing-kang-kou, a village Ch’ing-kang-kou 10 kilometres to the south-east from Lai Yang. In the month of October that same year, the remains were excavated by Tan’s close friend with his colleague, Austrian paleontologist Otto Zdansky. Although the original specimen was fairly complete, only the pieces could be recovered. The Holotype, PMU R.240, was found in the Jiangjunding Formation of the Wangshi Series dating from the Campanian. It is composed of the skull’s back that was straight and elongated.

Other species that were originally that were assigned to Tanius were later assigned into other genera. They include: Tanius prynadai named in 1939 by Anatoly Nikolaevich Ryabinin. This species has been assigned to Bactrosaurus and Tanius Chingkankouensis, named in 1998 by Yang Zhongjian and Tanius laiyangensis was named in the year 1976 by Zhen Shionan, that were later both considered as junior synonyms to Tsintaosaurus. However, a more recent study, Zhang et al. (2017) discovered the existence of T. sinensis as well as T. chingkankouensis were valid species of Tanius and T. laiyangensis was probably not legitimate. Zhang et al. (2019) revised the assessment of “Tanius” laiyangensis as a member of the saurolophine clade Kritosaurini The first member of the clade that originated from Asia.
