The Banas is a river which lies entirely within the state of Rajasthan in western India.

[1] The name "Banaas" literally translates as "forest-hope" (Ban-aas) meaning "Hope-of-the-forest" or 'Van Ki Aasha.'

The river originates in the Veron ka Math situated in Khamnor Hills of the Aravalli Range, about 5 km from Kumbhalgarh in Rajsamand district.

It flows northeast through the Mewar region of Rajasthan, then across Hadavati before meeting the Chambal near the village of Rameshwar in Sawai Madhopur District.

It drains the east slope of the central portion of the Aravalli Range, and the basin includes all or part of Ajmer, Bhilwara, Bundi, Chittorgarh, Dausa, Jaipur, Pali, Rajsamand, Sawai Madhopur, Sirohi, Tonk, and Udaipur districts.
