Shivnath River (or Seonath River) is the longest tributary of the Mahanadi River, which joins Changori in the Janjgir-Champa district in Chhattisgarh, India. It has a total course of 290 kilometres (180 mi). The name comes from the god Shiva in Hinduism.
Shivnath originates from Godari village in Gadchiroli district, Maharashtra, and flows northeast for 300 kms then joins the Mahanadi river near the town Shivrinarayan in Chhattisgarh. Some record origination at Panabaras Hill, 624 metres (2,047 ft) above sea level in the Ambagarh Chowki division of Rajnandgaon District of Chhattisgarh.
