The Trishuli River (Nepali: त्रिशूली नदी) is one of the major tributaries of the Narayani River basin in central Nepal. The river is formed by the merger of the Kyirong Tsangpo and the Lende Khola originating in Gyirong County of Tibet, which join together near the Rasuwa Gadhi on the Nepal–Tibet border. The valley of the river used to be the traditional trade route between the Kathmandu Valley and Tibet.
