Inayatullah Khan Sial (Punjabi: عنایت اللہ خان سیال) was an 18th-century Punjabi Muslim general and chieftain who served as the 14th Sardar of Jhang. He succeeded his uncle Walidad Khan, who died heirless in 1747 and ruled until his own death in 1787. He was succeeded by his son Sultan Mahmud.
The Jhang State reached its zenith under Inayatullah Khan, who won 22 battles against the Bhangi Misl and the Nawabs of Multan. He also retook Chiniot from the Bhangis, which was lost to them early in his reign.
