Dahar or Daher (Sindhi: ڏهر) is a Sindhi Sammat tribe. The Daharki city is named after this tribe.[citation needed] It is one of the prominent tribes in Ghotki.
Among others are the Bhuttos, Bhattis, Lakha, Sahetas, Lohanas, Mohano, Dahars, Indhar, Chachar, Dhareja, Rathors, Dakhan, Langah etc. The Mohano tribe is spread over Makran, Sind and southern Punjab. They are also identified with the "Mallah' of the Punjab and both have in common a sub-section called Manjari. All these old Sindhi tribes are known under the common nomenclature of Sammat.
The Sindhis were, as far as one can tell, descendants of the Hindu Rajputs who had been living in the country at the time of the Muslim conquest. The main tribes were Sammos, Sumros, Unars, Abros, Dahars, Mahars, Jokhios, Numrios, Jats and Mohanos. Most had long been settled as agriculturists on the alluvial plain.
