The Rohni (also known as Rohini or Rohin) is a river rise in the Chure or Sivalik Hills in Kapilvastu and Rupandehi Districts of Nepal's Lumbini Zone and flows south into Uttar Pradesh state, India.

One year, they did not have enough rain and finding that the paddy and other crops were beginning to shrivel up, cultivators on both sides wanted to divert the water from the Rohini river to their own fields.

They said that they were not prepared to go carrying their money and valuables to the opposite bank of the river in exchange for food.

The quarrel that started between the cultivators came to the ears of the ministers concerned, and they reported the matter to their respective rulers, and both sides prepared to go to war[2] Buddhist tradition holds that Siddhārtha Gautama crossed this river in his return to Kapilavastu.
