Sikkim National Congress (abbr. SNC) was a political party in the Kingdom of Sikkim. It was founded in 1962, through a merger of Swatantra Dal, Rajya Praja Sammelan, and dissidents of the then dominant parties, Sikkim State Congress and Sikkim National Party. Kazi Lhendup Dorjee was its leader. The SNC was formed to be a party representing all ethnic groups in Sikkim, as the previously dominating parties were divided on ethnic lines. It opposed the monarchy in Sikkim and worked for democratic reforms.
