The Pasur is a river in southwestern Bangladesh and a distributary of the Ganges. It continues the Rupsa River. All the distributaries of the Pasur are tidal.[1] It meets the Shibsa River in the Sundarbans. Near the sea, it becomes the Kunga River.[2] The Pasur is the deepest river in Bangladesh.
It is home to Sundarbans Firefly Sanctuary, a wildlife sanctuary for regional wildlife, including the Bengal tiger.
