River Churni is a stream in the Nadia district of the Indian state of West Bengal.^[1] It is a distributary of the Mathabhanga River, which in turn is a distributary of the Padma River at Munshiganj in the Kushtia District of Bangladesh. The Mathabanga divides into two rivers, the Ichamati and the Churni, near Majhdia in Nadia district.^[2]

The Churni flows through Shibnivas, Hanskhali, Aranghata, and Ranaghat, and finally joins River Bhagirathi at Shivpur (near Payradanga) ,Nadia . Its length is almost 53 kilometres (33 mi). The river's origin is at 23.40 North, 88.70 East and its confluence is at 23.13 North, 88.50 East.

According to an article in the International Journal of Current Research, the Churni is in part the remnants of an artificial canal ordered dug by a 17th-century maharajah (king). Changes to a nearby distributary of the Jalangi River resulted partly from water diversion down the canal. Sedimentation eventually dried up the upper part of the distributary, called the Anjana, while the canal and the lower Anjana formed the Churni. Another name for the Churni is Kata Kal or "dug river". ^{[citation needed]}

As recently as the 1930s, the river was an important route for water travel and trade. However, in the 21st century it has partly silted up, has many small islands, visible and submerged, and is no longer navigable.^{[citation needed]}
