Raymond Ndong Sima

Raymond Ndong Sima (born 23 January 1955 ) is a Gabonese politician who served as transitional Prime Minister of Gabon from September 2023 to May 2025. He was previously prime minister from February 2012 to January 2014.

Career Ndong Sima was born in Oyem, located in the north of Gabon, and studied in France.

Ndong Sima was appointed to the government as Minister of Agriculture, Livestock, and Rural Development on 17 October 2009.

In the December 2011 parliamentary election, in which the ruling Gabonese Democratic Party (PDG) won an overwhelming majority of seats, Ndong Sima was elected to the National Assembly as a candidate in Kyé, located in Woleu-Ntem Province.

Prime Minister Paul Biyoghe Mba resigned on 13 February 2012. President Ali Bongo then appointed Ndong Sima as prime minister on 27 February 2012. His appointment was considered noteworthy in that traditionally the post of Prime Minister was given to an ethnic Fang from Estuaire Province, while Ndong Sima was from Woleu-Ntem Province in the north—although he was also a Fang. Prior to his appointment, Ndong Sima had not been considered a particularly important figure on the political scene. Ona Ondo took office at a handover ceremony with Ndong Sima on 27 January.

In July 2015, Ndong Sima quit the PDG, complaining that the party was not open to criticism and different points of view. He also criticized the government's handling of finances since he left office. PDG Secretary-General Faustin Boukoubi responded that Ndong Sima was an opportunist and insisted that the PDG was internally democratic.

Following his resignation, Ndong Sima ran twice for president against Bongo in 2016 and 2023 but lost, obtaining less than 0.5% of the vote each time. Following the 2023 Gabonese coup d'état, he was reappointed by interim president Brice Oligui Nguema to become prime minister of a transition government on 7 September. The PDG is a member party of his second government. On 4 May 2025, he resigned from office, which marked the end of the transitional government.
