Saifoulaye Diallo (1 July 1923 – 25 September 1981) was a Guinean politician, lawmaker and cabinet member.
Diallo was educated at the École normale supérieure William Ponty in Dakar. While working as a civil servant in French West Africa, he was also a trade union activist, causing him to frequently move. As a member of the African Democratic Rally (RDA), he served in the National Assembly of France from 1956 to 1958.
In the 1957 Guinean Territorial Assembly election, Diallo was elected to and served as the first president of the assembly. After Guinea became independent in 1958, he continued as president of the country's National Assembly until 1963. Diallo was the political secretary of the ruling Democratic Party of Guinea – African Democratic Rally (PDG-RDA) and, after President Ahmed Sékou Touré, the de facto number-two statesman during the first five years of the Republic of Guinea. In January 1963 he entered the government, where he would serve as Minister of State, at various points responsible for finance and planning.
In May 1969, Diallo replaced Louis Lansana Béavogui as Minister of Foreign Affairs. After leaving the position as Minister of Foreign Affairs for health reasons in June 1972, he held the largely ceremonial post of Minister to the Presidency until 1976.[1]
