Fahd bin Abdulaziz Al Saud, Custodian of the Two Holy Mosques (Arabic: فهد بن عبد العزيز آل سعود Fahd ibn ‘Abd al-‘Azīz Āl Sa‘ūd; 16 March 1921 – 1 August 2005) was King of Saudi Arabia from 1982 to 2005.
One of 45 sons of Saudi founder Ibn Saud, and the fourth of his six sons who have ruled the Kingdom (Saud, Faisal, Khalid, Fahd, Abdullah and Salman), 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 his 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 in 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 in August 2005.
King Fahd is credited for having introduced the Basic Law of Saudi Arabia in 1992.
