The Haoling Formation is a Mesozoic geologic formation in the Ruyang Basin of Henan, Province, central China. Dinosaur remains are among the fossils that have been recovered from the formation.
The Haoling Formation was originally treated as part of the Mangchuan Formation and considered to be of Paleocene age before being recognized as Mesozoic in age.Bureau of Geology and Mineral Resources of Henan Province. 1989.

Discovery of a gigantic sauropod femur in Ruyang, Henan, China and its stratigraphic significance. Geol Bull China. 25(11):1299–1302. A 2012 paper divided the Mangchuan into the Xiahedong, Haoling, and Shangdonggou Formations, assigning the dinosaur-bearing horizon to the Haoling Formation and constraining the age of the Haoling as Aptian-Albian based on fieldwork and invertebrate and microfossil assemblages.Xu, L., Pan, Z.C., Wang, Z.H., Zhang, X.L., Jia, S.H., Lü, J.C., Jiang, B.L., 2012.
