Ahmad Mirfendereski (Persian: احمد میرفندرسکی; 9 May 1918 – 2 May 2004) was an Iranian diplomat, politician and the last minister of foreign affairs of the Shah era in Iran.

[4][5] Mirfendereski was appointed foreign minister to the cabinet led by Shahpour Bakhtiar in January 1979, replacing Abbas Ali Khalatbari in the post.

[6][7] His term lasted very short, just 37 days, and ended in February 1979 when an Islamic revolution took place in the country.

[7] After leaving office, Mirfendereski was arrested and put at Qasr prison in Tehran where other senior officials were also detained.

[6][11] In 1984, Mirfendereski declared in Paris that the Shah's cancer had been diagnosed in 1974, six years before his death in Egypt on 27 July 1980 and that it had been kept secret until the revolution.
