Abdullah bin Faisal Al Saud (Arabic:عبد الله بن فيصل بن تركي بن عبد الله بن سعود آل سعود) (born 1951) is a member of House of Saud. Between October 2015 and April 2017 he was Saudi Arabia's ambassador to the United States.

Abdullah bin Faisal was born in Taif in 1951. His mother, Luluwah bint Abdulaziz, is the full sister of Sudairi Seven. He has six siblings and is the oldest of them. His brother, Sultan bin Faisal bin Turki, was killed in a car crash at age 41 on 23 July 2002 while coming from Jeddah to Riyadh to participate in funeral prayers for Prince Ahmed, son of Prince Salman, who has been the King of Saudi Arabia since 2015.

Prince Abdullah's family on the father's side is directly descended from Saud bin Faisal. Saud's rule as well as that of his brother Abdullah marked the end of the second Saudi state after an invasion of Ottomans early in the 19th century.

Prince Abdullah received elementary and secondary education in Saudi Arabia. He then went to the United Kingdom for higher education where he studied engineering.

Prince Abdullah's early career as an engineer involved both technical and management positions. He assumed the responsibility of the coordination of various studies for the two industrial cities, and later for the industrial security and safety sector.

Abdullah bin Faisal began his career at the Royal Commission for Jubail and Yanbu immediately after its establishment in 1975. He served as the acting secretary general of the Royal Commission from 1985 to 1987. Then, he was appointed secretary general of the royal commission in 1987. Next, he was appointed chairman of the body in 1991 and he served as chief executive officer of the commission and chairman of its board of directors.

In April 2000, Saudi Arabian General Investment Authority (SAGIA) was created, responsible for promotions of the foreign and domestic investments in Saudi Arabia. Prince Abdullah was appointed governor of SAGIA with the rank of minister in 2000. His tenure lasted until 2004 when he resigned from this post. It was speculated that since he was frustrated with the government’s bureaucratic approach and the slow pace of the reforms in the country, he left SAGIA.
