The 18th government of Turkey (16 January 1949 – 22 May 1950) is also referred to as the Günaltay government.
Hasan Saka of the Republican People's Party (CHP), who was the previous prime minister, resigned on 14 September 1949. President İsmet İnönü, upon the suggestion of Hilmi Uran, the secretary general of his party, assigned Şemsettin Günaltay as the new prime minister. Günaltay was a scholar of religion, philosophy and history. A scholar of religion as the prime minister of a party which was known to be the champion of secularism was quite unexpected.
In the list below, the cabinet members who served only a part of the cabinet's lifespan are shown in the column "Notes".
