[[File:Seal_of_Sikkim_color.png|thumb|250px|Seal of Sikkim)] The Chogyal (Tibetan: ཆོས་རྒྱལ, Wylie: chos rgyal) were the monarchs of the former kingdoms of Sikkim and Ladakh, which were ruled by separate branches of the Namgyal family. The Chogyal, or divine ruler, was the absolute potentate of Sikkim from 1642 to 1975, when monarchy was abrogated and its people voted in a referendum to make Sikkim India's 22nd state.
However, Chogyal meaning "Dharma Raja" or "Religious King" is a title which was also conferred upon a special class of temporal and spiritual rulers.
In Bhutan the Chogyal were also known as the Dharmaraja, or Kings of Dharma, and Shabdrung. In this context, the Chogyal was a recognized reincarnation (or succession of reincarnations) of Shabdrung Ngawang Namgyal, the 17th Century Tibetan-born founder of Bhutan. A position of supreme importance, the Bhutanese Chogyal was above both the highest monastic authority, the Je Khenpo, and the highest temporal ruler, the Deb Raja or Druk Desi. The Tibetan Dzogchen teacher Namkhai Norbu holds this title as a recognized reincarnation of Ngawang Namgyel, and there is also a line of claimed reincarnations in Bhutan and India. The remainder of this article deals with the Chogyal of Sikkim. For Bhutan, see Shabdrung.
[[File:Gods-p a-b.JPG|thumb|250px|Guru Rinpoche)] From 1642 to 1975, Sikkim was ruled by the Namgyal Monarchy (also called the Chogyal Monarchy), founded by the fifth-generation descendants of Guru Tashi, a prince of the Minyak House who came to Sikkim from the Kham district of Tibet (link to Tibet page?). Chogyal means 'righteous ruler,' and was the title conferred upon Sikkim's Buddhist kings during the reign of the Namgyal Monarchy.
The reign of the Chogyal was foretold by the patron saint of Sikkim, Guru Rinpoche. The 8th-century saint had predicted the rule of the kings when he arrived in the state. In 1642, Chogyal Phuntsog Namgyal was crowned as Sikkim's first ruler in Yuksom. The crowning of the king was a great event and he was crowned by three revered lamas who arrived there from three different directions, namely the north, west and south.

The son from the first marriage of Palden Thondup Namgyal, Wangchuk Namgyal, was named the 13th Chogyal after his father's death on 29 January 1982, but the position no longer confers any official authority.
