Raja Dahir (Sindhi: राजा दाहिर, راجا ڏاھر b. 679, d. 712) was a Sindhi Hindu ruler. He was the last Sindi Hindu in Sindh and parts of Punjab in what is Pakistan today. In the early part of the Muslim conquest in the Indian subcontinent, Muhammad bin Qasim al-Thaqafi took control of Dahir's kingdom for the Umayyad Caliphate.
Today, Raja Dahir is well liked by many different people. Many Sindhi Muslims (Sunni and Shiites) like him for defending both Sindh and Muhammad Bin Allafi. Hindus like him for defending India and the Hindus. He is liked by manyZoroastrians for defending Sindh for them.
