The Relli River is a small Himalayan river in the Indian states of Sikkim and West Bengal, flowing near Kalimpong. The source of the Relli lies in Sikkim at an elevation of 1,700 metres (5,500 ft). The river runs less than 10 kilometres (6 mi) from central Kalimpong, separated by Deolo Hill. It flows into the Teesta River about 17 kilometres (11 mi) to the south of central Kalimpong.
The northerly slopes along the Relli in Upper Echhay Sherpagaon, in Sikkim, are home to a cluster of some 50 Sherpa households. The village of Relli is located on its banks downriver from Kalimpong, connected to the city by road and trails.
Rinchingpong, a tourist area situated in the northern part of Kalimpong, overlooks the Relli. The Relli is a popular weekend destination among Kalimpong locals for attractions including local cuisine, picnicking spots, boating, and recreational fishing. A Wayside Inn managed by the West Bengal Tourism Department is located nearby.
