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.

Yang et al. performed a phylogenetic analysis and found Taohelong to be the sister taxon to Polacanthus foxii, making it the first polacanthine to be described from Asia.
