Mipham Sonam Wangchuk Drakpa Namgyal Palzang (Tibetan: མི་ཕམ་བསོད་ནམས་དབང་ཕྱུག་གྲགས་པ་རྣམ་རྒྱལ་དཔལ་བཟང, Wylie: Mi pham bsod nams dbang phyug grags pa rnam rgyal dpal bzang, died 1671) was a king in Central Tibet. He belonged to the Phagmodrupa Dynasty which reigned in Tibet, or parts of it, from 1354 to the early 17th century, and was the last prince of the dynasty.
Mipham Sonam Wangchuk Drakpa Namgyal Palzang was the eldest son of the prince Kagyud Nampar Gyalwa (died 1623) and the grandson of king Ngawang Drakpa Gyaltsen (died 1603/04). The circumstances around his accession are extremely obscure. The materials worked out by Giuseppe Tucci suggests that he succeeded to the throne by c. 1600. In the early years of the 17th century he is intermittently mentioned in the sources with the ruling title (desi). However, according to the investigation Olaf Czaja, Ngawang Drakpa Gyaltsen was actually succeeded by a scion of a rival branch, Mipham Wanggyur Gyalpo, in 1604. Only some time after the death of the latter in 1613, Mipham Sonam Wangchuk Drakpa Namgyal Palzang would have been consecrated as ruler. Whether his father Kagyud Nampar Gyalwa ever ruled in his own name is not clear. Whatever the case, by this time the dynasty had since long been eclipsed by other political and religious centers. However, in the early years of the 17th century the authority of the Phagmodrupa revived somewhat in the Ü region (East Central Tibet). This was due to their good connections with the Gelugpa. The main political division at this time was between the Gelugpa sect, aided by their Mongol allies, and the Karmapa and their patrons of the Tsangpa dynasty. The Phagmodrupa kings were traditionally friendly disposed towards the Gelugpa leaders, the Dalai Lamas.
