Late Kazi Lhendup Dorjee (October 11, 1904-July 28, 2007) was the chief architect of Sikkim merger and became the first chief minister when Sikkim became a part of the Indian Union.

He was a member of INC after 1975 and Sikkim National Congress before 1975. Sikkim became a part of India when late Indira Gandhi was the Prime Minister.
