Harsawa is a village located in the Sikar district of Shekhawati region, in Rajasthan state, India. Harsawa is within the Fatehpur Tehsil, 8 km south along National Highway-11 from Fatehpur town. Sand dunes of the Thar Desert can be seen from Harsawa.
As of 2001[update], the village had a total population of 1695. After the defeat of the last Hindu King of Delhi, Prithviraj Chauhan, in the second Battle of Tarain (1192), the Jats in his army moved to the countryside and settled as cultivators at various places in India. Initially Saharan gotra Jats came to this area and started temporary cultivation, but after some time they left. Subsequently, Nehra gotra Jats from the nearby village of Banthod migrated to this place and started cultivation. One of these Nehra gotra Jats was Harsa Nehra, who founded the village of Harsawa in 1287 AD. Later settlers included Dhaka gotra Jats from Juliasar and Datujala villages, Thori gotra Jats from Ramsisar, Bhaskar gotra Jats from Rajas, Lamoria gotra Jats from Antroli and Dhayal gotra Jats from Fuskani villages.
