Heimaogou is a fossil site in Xixia County in the Southwest of the province of Henan in China.
In 1992 or 1993, a group of farmers from around the area dug up some fossilized nest material from this site. In 2015, paleontologists traveled back to this site with one of the farmers to properly note the location and specimens of the locality.
At least one species of dinosaur was discovered here: Beibeilong sinensis.
No information can be found for the name of this site; it might be named after one of the farmers who discovered it.
