Huy (or H'ui, Hui, Chao Huy, Brhat Chao, 1780–1840) was prince-governor (Chao Mueang Nakhon Champasakti) of the Siamese vassal Kingdom of Champasak in southern Laos from 1828 to 1840.^[1][2]

Prince (Brhat Chao) Huy was a son of the Uparaja of Champasak, Unga (who had ruled Champasak as a Siamese vassal from 1778 until he was murdered in 1781 on the orders of King Taksin). Huy was raised as a page in the palace of King Rama I of Siam in Bangkok and served in the Siamese army, rising to the rank of general. In 1827, he captured king Nyô during the Laotian rebellion and brought him to Bangkok, where he was thrown from the roof of a temple. As a reward, Huy was appointed as the prince-governor of Champasak in his place.^[1]
