Turki (II) bin Abdulaziz Al Saud (Arabic: تركي الثاني بن عبد العزيز بن عبد الرحمن آل سعود‎‎, Turkī ṯ-Ṯānī bin ʿAbd al-ʿAzīz ʿĀl Saʿūd) (1934 – 11 November 2016) was a member of the House of Saud.

Prince Turki was born in 1934. He was a member of the Sudairi Seven, a powerful faction of brothers within the Al Saud. His parents were King Abdulaziz and Hassa Al Sudairi. He was known as "the second" (الثاني ath-thānī) because he was the second son born to King Abdulaziz named "Turki". The first Prince Turki was Abdulaziz's first son who died in 1919 due to Spanish flu.

Prince Turki studied at the Princes' School established by his father.

Turki bin Abdulaziz assumed the Riyadh principality delegation on 10 October 1957, because Prince Salman, (later to become King Salman) then-Riyadh governor, travelled with King Saud to Lebanon. In 1960, the approval of the King was issued to assign Prince Turki as the governor of the Riyadh Province in the period of the formal vacation of Prince Salman. Turki bin Abdulaziz was appointed the deputy defense minister in July 1969 by a royal order. His tenure lasted for nine years and he was forced to resign from office due to his marriage in 1978.

After his falling-out with other princes and joining with the free princes group, Turki bin Abdulaziz moved to Cairo and lived there in self-imposed exile for a time. However, other research on the Free Princes Movement does not mention his name as part of this group; so an alternate explanation of his self-exile in Cairo offers that ir occurred as a result of an intra-family dispute due to his marriage to Hind Al Fassi (See also below and Personal life section).
