Taohelong is a genus of nodosaurid dinosaur known from Lower Cretaceous rocks in north-central China. Taohelong is based on Gansu Dinosaur Museum (GSDM) 00021, fossils including a tail vertebra, ribs, a left ilium (the main bone of the hip), and bony armor recovered from the Hekou Group in the Lanzhou-Minhe Basin. The animal's armor includes part of a "sacral shield", a carpet of osteoderms over the hips found in some other ankylosaurians. Taohelong was named and described in 2013 by Yang Jing-Tao, You Hai-Lu, Li Da-Qing, and Kong De-Lai. The type species is Taohelong jinchengensis. The generic name means "dragon (long) of the river (he) Tao". The specific name refers to the provenance at Jincheng.
