Penlop of Trongsa (Dzongkha: ཀྲོང་གསར་དཔོན་སློབ་; Wylie: Krong-gsar dpon-slob), also called Chhoetse Penlop (Dzongkha: ཆོས་རྩེ་དཔོན་སློབ་; Wylie: Chos-rtse dpon-slob; also spelled "Chötse"), is a Dzongkha title meaning "Governor of the Province of Trongsa (Chhoetse)". It is generally given to the heir apparent of the Kingdom of Bhutan. The most recent holder of the title was King Jigme Khesar Namgyel Wangchuck, who was then a prince (Dzongkha: dasho, gyalsey). Although the current heir presumptive is Prince Jigyel Ugyen Wangchuck, the title is reserved for the officially designated heir apparent, which is subject to change by the reigning king. Also, the reigning Druk Gyalpo may retain the office or award it to another person after coronation. The proper reference style is His Royal Highness Trongsa (Chhoetse) Penlop.
Penlop is a title roughly translating to "Provincial Governor" or the European title "Duke". The crown prince holds the title "Penlop of Trongsa", or "Trongsa Penlop", which is the title held by the House of Wangchuck before its ascendancy to the throne. Originally, there were Penlops for each of the nine provinces of Bhutan, but they were consolidated under the control of the 12th Penlop of Trongsa Ugyen Wangchuck when he became the first Druk Gyalpo.
