Jianchang (Chinese: 建昌; pinyin: Jiànchāng) is a county of Huludao City in the southwest of Liaoning province, China. It is the largest division of Huludao, with an area of 3,195 square kilometres (1,234 sq mi),[2] and population of 450,000 in 2020, located in mountainous terrain 85 kilometres (53 mi) west of that city, serviced by China National Highway 306. The Weizhangzi–Tashan railway also passes through the County.[3]

Near the border with Hebei province lies the Jianchang Longtan Grand Canyon, home to wide variety of plants and animals. In 2009 a Troodontid dinosaur fossil with feathers was discovered in Jianchang. It is the earliest known such fossil and provides evidence for the link between dinosaurs and birds.[4] Also found here, in Jiufotang Formation rocks, was the early modern bird Schizooura.[5]
