Bhumibol Adulyadej (Thai: ภูมิพลอดุลยเดช; RTGS: Phumiphon Adunyadet; born 5 December 1927) is the King of Thailand. He is also known as Rama IX, as he is the ninth monarch of the Chakri Dynasty. Having reigned since 9 June 1946, he is the world's longest-serving current head of state and the longest-reigning monarch in Thai history, serving for 69 years, 112 days.

King Bhumibol is respected and revered by most Thais. In 1957, the overthrow of his then government was justified with allegations of lèse majesté, which is offence against the dignity of the monarch, punishable under Thai law. Although Bhumibol did invite public criticism in a 2005 speech, the lèse majesté laws have not been revoked by the Thai parliament.

Forbes estimated Bhumibol's fortune—including property and investments managed by the Crown Property Bureau (CPB), a unique body that is neither private nor government-owned—to be   US$30 billion in 2010, and he was the leader of the magazine's list of   "The World's Richest Royals" from 2008 to 2013. In May 2014, Bhumibol's wealth was once again listed as US$30 billion. Officially the assets managed by the CPB are owned by the crown as an institution, not Bhumibol Adulyadej as an individual.
