Abdullah bin Faisal Al Saud (Arabic: عبد الله بن فيصل آل سعود ʿAbd Allāh bin Fayṣal Āl Suʿūd; 18 June 1923 – 8 May 2007) was a Saudi Arabian businessman, politician, and poet who held multiple posts in the Saudi government throughout the 1940s and 1950s. Prince Abdullah was the eldest son of King Faisal. He served as the governor of Hejaz during the reign of his grandfather King Abdulaziz, and as the minister of health and interior during the reigns of his grandfather and his uncle King Saud. These positions made him one of the most powerful Saudi Arabian royals of his time.
 Prince Abdullah was born in Riyadh in 1923. However, some sources list his birth year as 1921 or 1922. He was the eldest son of King Faisal. His mother was Sultana bint Ahmed Al Sudairi, sister of Hussa bint Ahmed Al Sudairi.
 It is believed that Prince Abdullah was the second grandson of King Abdulaziz after Faisal bin Turki who was born in 1918. The marriage of Prince Faisal and Sultana bint Ahmed was prearranged while Prince Faisal was travelling abroad. They never saw each other until the marriage and later divorced.
 Abdullah bin Faisal completed his education in Mecca in 1939.
 Abdullah bin Faisal assumed a number of government positions. He started his political career in 1945 when he disputed his half-uncle Mansour's appointment as acting viceroy of Hejaz and actually assumed the office one year later.
 Prince Abdullah was the first minister of health of Saudi Arabia and appointed to the post in 1950. Then, he was named minister of interior in 1951, being the first interior minister of the Kingdom. He served in this post during the reign of King Abdulaziz and also, of King Saud. His appointment as minister of health and of interior was a move to make him equal in status to then-minister of defense Prince Mishaal. His term lasted until March 1959 when he resigned, and he was replaced by his father, Crown Prince Faisal, in the post of interior minister.

In addition, he founded Abdullah Establishment for Trading and Industry in Jeddah in 1978 and the SIGMA (Saudi Investment Group and Marketing) company in 1979. The chairman and CEO of the latter was his son, Prince Saud.
 Prince Abdullah's business partners included the sons of Rashad Pharaon, Ghaith and Mazen. He was one of the founders of the Dar Al Maal Al Islami Trust which was initiated by his half-brother Mohammed bin Faisal Al Saud in 1981.

 A composer of both classical and colloquial poetry, his works include the collection The Inspiration of Deprivation (Min Wahye al Hirman), 1980.
