The Ghana News Agency (GNA) is the official news agency of the country of Ghana.
 It was founded in 1957 by Kwame Nkrumah as part of a "network of coercive and partisan institutions," in a concerted effort to present a more favorable view of the country to the outside world and to control the flow of information nationally. "
The New York Times" reported in 1964 that most of the agency's news came from Reuters (it had "only a few correspondents abroad"); the agency functioned as a gatekeeper in that it disseminated international news to the Ghanaian press, and deleted any international news critical of the Ghanaian leadership immediately, thus preventing such news from reaching the country's newspapers and radio stations.
 Until the rise of the Pan African News Agency, the GNA was considered one of the most efficient news agencies in Africa, spreading what Nkrumah called the "clear ideology of the African Revolution" and contributing to "African and Ghanaian emancipation."
