Phuntsog Namgyal (Sikkimese: ཕུན་ཚོག་རྣམ་རྒྱལ་; Wylie: phun tshog rnam rgyal) (1604–1670) was the first Chogyal (monarch) of Sikkim,[1] now an Indian state.

Phuntsog was a fifth generation descendant of Khye Bumsa, a 13th-century prince from the Mi-nyak House in Kham in Eastern Tibet.

According to legend, Guru Rinpoche, a 9th-century Buddhist saint had foretold the event that a Phuntsog from the east would be the next chogyal of Sikkim.

The crowning took place Norbughang near Yuksom on a stone slab in a pine covered hill, and he was anointed by sprinkling water from a sacred urn.

Phuntsog is credited with creating "Lho-Mon-Tsong-Sum", the idea of unity between Bhutias, Lepchas, and Limbus that forms the core of Sikkimese national identity.
