Nuon Chea (; born Lao Kim Lorn; 7 July 1926 – 4 August 2019), also known as Long Bunruot () or Rungloet Laodi ( ), was a Cambodian communist politician and revolutionary who was the chief ideologist of the Khmer Rouge. He also briefly served as acting Prime Minister of Democratic Kampuchea.

In 2014, Nuon Chea received a life sentence for crimes against humanity, alongside another top-tier Khmer Rouge leader, Khieu Samphan, and a further trial convicted him of genocide in 2018. These life sentences were merged into a single life sentence by the Trial Chamber on 16 November 2018. He died while serving his sentence in 2019.
