The Sarsuti river, originating in Sivalik Hills and flowing through the palaeochannel of Yamuna, is a tributary of Ghaggar river in of Haryana state of India.

[2][3][1] Its course is dotted with archaeological and religious sites dating back to post-Harrapan Mahabharata sites from Vedic period, such as Kapal Mochan, Kurukshetra, Thanesar, Brahma Sarovar, Jyotisar, Bhor Saidan and Pehowa.

[1] The Sarsuti is a small ephemeral stream that rises in the Sivalik Hills of south-eastern Himachal Pradesh in India,[4] and flows through Haryana.

Further downstream on the banks of the Ghaggar stands an old derelict fort [at sirsa city] named Sarsuti.

[4] According to Valdiya and Danino, Sarsuti is a corruption of the word Sarasvati, and the 6–8 km wide channel of the Sarsuti–Ghaggar system may have once been the Sarasvati River mentioned in the Rig Veda.
