Helian Ding (; died 432), nickname Zhifen (直獖), was the last emperor of the Xiongnu-led Chinese Hu Xia dynasty. He was a son of the founding emperor Helian Bobo (Emperor Wulie) and a younger brother of his predecessor Helian Chang. After Helian Chang was captured by rival Northern Wei's army in 428, Helian Ding took the throne himself and for several years tried to resist Northern Wei attacks, but by 430 he had lost nearly his entire territory. In 431, he attempted to head west to try to attack Northern Liang and seize its territory, but on the way, he was intercepted by Tuyuhun's khan Murong Mugui (慕容慕璝) and captured, ending Xia. In 432, Murong Mugui turned him over to Emperor Taiwu of Northern Wei, who had him executed.
