The Rangeet or Rangit (Devanagari रंगीत) is a tributary of the Teesta river, the largest river in the North Indianstate of Sikkim and Kalimpong Subdivision. The Rangeet river originates in the Himalayan mountains in West Sikkim district. A perennial river, it is fed by the melting snow of the Himalayas in early summer and the monsoon rains in June–September. It is popular among rafting enthusiasts owing to its turbulent waters. The river flows past the towns of Jorethang, Pelling and Legship. During its final few kilometres, it joins the Teesta River at a confluence known as Tribeni, a popular picnic spot. The Rangeet river has an NHPChydropower plant with a capacity of 60 megawatts (80,000 hp) capacity in Sikkim.
