Harenadraco (meaning "sand dragon") is an extinct genus of troodontid theropod dinosaurs from the Late Cretaceous Baruungoyot Formation of Mongolia. The genus contains a single species, H. prima, known from a fragmentary skeleton. Harenadraco represents the first troodontid known from the Baruungoyot Formation. Since members of this family are also known from the Nemegt and Djadochta Formations, the discovery of Harendraco indicates that troodontids were important faunal components of every formation within the Nemegt Basin.

== Discovery and naming == thumb|left|Outcrops of the Baruungoyot Formation (Hermiin Tsav locality), which produced the Harenadraco holotype and many other dinosaur specimens The Harenadraco holotype specimen, MPC-D 110/119, was discovered in 2018 in sediments of the Baruungoyot Formation (Hermiin Tsav locality) in Ömnögovi Province, Mongolia. The specimen consists of a fragmentary and partially articulated skeleton, comprising pieces of the right ilium, the end of the right femur, and several bones from the left hind leg, including the top of the femur, the end of the tibiotarsus, the second through fourth metatarsals, and several pedal phalanges. Some unidentified bone fragments are also associated with the skeleton.
