Tensung Namgyal (Sikkimese: བསྟན་སྲུང༌རྣམ་རྒྱལ་; Wylie: bstan srung rnam rgyal) (1644–1700)[1] was the second Chogyal (monarch) of Sikkim.

He succeeded his father Phuntsog Namgyal in 1670 and moved the capital from Yuksom to Rabdentse near Geyzing.

He had three wives from Bhutan, Nambi Onmo, Tibet, Lhacham Pema Putik, and a Limbu princess from the Arun valley, Thungwamukma.

After establishing Rabdentse as his new capital he built a palace and asked his Limbu Queen to name it.

[citation needed] Tensung had an affair with Numbong, a Lepcha noblewoman married to Tasa Aphong, a prominent Lepcha tumyang (village leader), who had a son by him named Yugthing Arub, who would become Sikkim's treasury official during the reign of Tensung's son, Chagdor.
