Hu Nim (Khmer: ?? ???, 25 July 25, 1930 or 1932 – 6 July 1977), alias "Phoas" (????), was a Cambodian Communist intellectual and politician who held a number of ministerial posts.
His long political career included spells with the Sangkum regime of Prince Norodom Sihanouk, the Communist guerrilla resistance, the GRUNK coalition government-in-exile, and the administration of Democratic Kampuchea, when the country was controlled by the Communist Party of Kampuchea (the Khmer Rouge).
Nim had a reputation as one of the most independent-minded and outspoken members of the Khmer Rouge, and was eventually arrested, tortured and executed at Tuol Sleng security prison in 1977 during a Party purge.
