Feni River is a river in southeastern Bangladesh and Tripura state of India. It is a trans-boundary river with an ongoing dispute about water rights. The Feni River originates in South Tripura district and flows through Sabroom town and then enters Bangladesh. Muhuri River, also called Little Feni, from Noakhali District joins it near its mouth. The river is navigable by small boats as far as Ramgarh, about 80 kilometres (50 mi) upstream.
