The Dhaleshwari River (, Dhôleshshori) is a distributary, 160 km long, of the Jamuna River in central Bangladesh. It branches off the Jamuna near the northwestern tip of Tangail District. After that it divides into two branches: the north branch retains the name Dhaleshwari and merges with the other branch, the Kaliganga River at the southern part of Manikganj District. Finally the merged flow meets the Shitalakshya River near Narayanganj District. This combined flow goes southwards to merge into the Meghna River. Average depth of river is 122 ft and maximum depth is 265 ft. Water pollution of the Dhaleshwari River by the textile industry has been described by academics as an ecocide.
