Mongla Port the second largest river port located 48 km south of Khulna town. The port was developed initially about 18 km up at Chalna, which was opened to foreign vessels as an anchorage on 11 December 1950. The anchorage was shifted to Mongla in 1954 as the place could accommodate sea-going vessels with greater draughts. The port of Mongla had long retained its name Chalna. Mongla is situated on the confluence of the rivers pasur and Mongla at mouza Selabunia of rampal upazila of bagerhat district. During the Pakistan period, the administration of the port was under a port director, whose main office was at Khulna.
