River (Bengali: মেঘনা নদী) is an important river in Bangladesh, one of the three that forms the Ganges Delta, the largest on earth fanning out to the Bay of Bengal. Being a part of the Surma-Meghna River System, Meghna is formed inside Bangladesh by the joining of different rivers originating from the hilly regions of eastern India. The river meets Padma River in Chandpur District. The river ultimately flows into the Bay of Bengal in Bhola District.
Major tributaries of the Meghna include the Dhaleshwari River, Gumti River, and Feni River. The Meghna empties into the Bay of Bengal via four principal mouths, named Tetulia, Shahbazpur, Hatia, and Bamni.

It also drains one of the world's heaviest rainfall areas (eg about 1,000 cm at Cherapunji, Meghalaya, India). East of brahmaputra-jamuna river system is Surma-Meghna River System. The surma originates in the hills of Shillong and Meghalaya of India.

On reaching the border with Bangladesh at Amalshid in Sylhet district, Barak bifurcates to form the steep and highly flashy rivers Surma and kushiyara.
