King Fahd bin Abdul Aziz Al Saud, Custodian of the Two Holy Mosques, (16 March 1921 – 1 August 2005) was the King of the Kingdom of Saudi Arabia, Head of the House of Saud as well as Prime Minister. One of forty-five sons of Saudi founder Ibn Saud, and the fourth of his five sons who have ruled the Kingdom (Saud, Faisal, Khalid, Fahd, and Abdullah), Fahd ascended to the throne on the death of his half-brother, King Khalid, on 13 June 1982.
Fahd was appointed Crown Prince when Khalid succeeded their half-brother King Faisal, who was assassinated in 1975. Fahd was viewed as the de facto prime minister during King Khalid's reign in part due to the latter's ill health.
Fahd suffered a debilitating stroke 29 November 1995, after which he was unable to continue performing his full official duties. His half-brother, Abdullah, the country's Crown Prince, served as de facto regent of the kingdom and succeeded Fahd as monarch upon his death on 1 August 2005.
