The Surma (Bengali: সুরমা নদী, romanized: Śurmā nôdī, Sylheti: ꠡꠥꠞꠝꠣ ꠉꠣꠋ, romanized: Śurma gaṅ) is a major river in Bangladesh, part of the Surma-Meghna River System. It starts when the Barak River from northeast India divides at the Bangladesh border into the Surma and the Kushiyara rivers. It ends in Kishoreganj District, above Bhairab Bāzār,[1] where the two rivers rejoin to form the Meghna River, which ultimately flows into the Bay of Bengal in Bhola District.
