Jia Sidao (August 25, 1213 – October 1275), courtesy name Shixian, was a Chinese government official who served as chancellor of the Southern Song dynasty of China. He was the younger brother of a concubine of Emperor Lizong, who had the special favor of Emperor Duzong. Jia Sidao took part in a land nationalization program in the 1260s and was involved during the Mongol conquest, especially during the Battle of Xiangyang and the siege of Ezhou. He was assassinated by a Song dynasty court-designated sheriff charged with his custody in 1275.
