Turag River (Bengali: তুরাগ নদ; [t̪uraɡ nɔd̪]) is the upper tributary of the Buriganga, a major river in Bangladesh. The Turag originates from the Bangshi River, the latter an important tributary of the Dhaleshwari River, flows through Gazipur and joins the Buriganga at Mirpur in Dhaka District. It is navigable by boat all year round.
The Turag suffers from infilling along its banks, which restricts its flow. Sedimentation that reduces the flow may have begun as early as the 1950 Assam–Tibet earthquake. It also suffers from acute water pollution. While attempts have been made to marginally widen the river, the majority of industry has made little effort to follow environmental laws and the water has become visibly discolored and polluted.
