Sam Sary (Khmer: ?? ????; 6 March 1917 – disappeared in 1962) was a Cambodian politician who participated in the so-called Bangkok Plot against Prince Norodom Sihanouk.
He was a son of Sam Nhean, a prominent politician in the 1940s, and father of Sam Rainsy, the leader of Cambodia's main opposition party.
He was a close confidant of the then Prince Norodom Sihanouk but had a falling-out with the Prince when he was exposed in corruption, selling import licenses and a second time during his tenure as a Cambodian ambassador to London in 1958, for beating his pregnant servant.
He was alleged to have beaten her so badly that she escaped to the protection of the London police.
The scandal made headlines in the London tabloids and he was recalled to Cambodia and stripped of all of his duties.
