The Kalhora dynasty (Sindhi: ڪلهوڙا راڄ, romanized: Kalhora Raj) was a Sunni Muslim dynasty of Sindhi Kalhora origin based in the region of Sindh in what is now Pakistan. They claimed an Arab origin. The dynasty ruled Sindh and parts of the Punjab region between 1701 and 1783 from their capital of Khudabad, before shifting to Hyderabad from 1768 onwards. They were assigned to hold authority by the Mughal Grand Vizier Mirza Ghazi Beg and later formed their own independent dynasty, and they were known as the "Kalhora Nawabs" by the Mughal emperors.
