Surinyavong II (also spelled Surinyavongsa; Lao: ເຈົ້າສຸລິຍະວົງສາ; died 1791 in Bangkok) was the king of Luang Phrabang from 1771 to 1788.
[2] He deeply hated Ong Boun, the king of Vientiane, whom he blamed for instigating the Burmese army attack on Luang Phrabang of 1765.
[1] The Siamese king Taksin seized Lanna in 1776, now Luang Phrabang was able to shake off Burmese suzerainty.
In 1778, Surinyavong informed that a Siamese army under Chao Phraya Chakri (later Rama I) was sent to invade Vientiane.
Since then, Luang Phrabang was forced to pay tribute, an annual bunga mas.
