Nu ( full throne name Somdet Chao Brhat Anuya; * in the later 18th century, † 1811) was in 1811 for three days of the dependent rulers of Siam Kingdom of Champasak.
Nu was the son of Prince No Mueang and thus grandson of King pothi of Champasak (reigned 1737-1791 ). Nu was educated at court and in Bangkok where he stayed as a hostage at the court of King Rama I.. In 1811 he was appointed by the Siamese king, but he died three days after his enthronement. He left three sons.
This was followed by a two-year interregnum, which was ended by the establishment of King Phom Ma Noi (reigned 1813-1820 ).
