Jian changmaensis is an extinct species of microraptorine theropod dinosaur known from the Early Cretaceous Xiagou Formation of China. J. changmaensis is the only species in the genus Jian, known from a pectoral girdle and partial forelimb. After the discovery of more than 100 bird fossils in the formation, this specimen is the first non-avian dinosaur to be described from it.
