Abdul Rahman, the first of King Abdulaziz's sons to study in the West, received a Bachelor of Arts degree from the University of California, Berkeley and graduated from the California Military Academy.

He was the counsellor for royal family affairs during the mid-1970s. Abdul Rahman replaced his brother, Prince Turki II, as the kingdom's deputy minister of defense and aviation in 1978 when Turki resigned; before that, he was a businessman. He held the post until 5 November 2011. During the 1980s, when he was deputy minister, Abdul Rahman reportedly provided food service to the ministry with his own company.

During Prince Sultan’s absence from the Kingdom for medical treatment, he increased his activity at the ministry. Abdul Rahman was often described as becoming more irritable with age.

He was relieved from his post as deputy minister on 5 November 2011. According to Al-Quds Al-Arabi, Abdul Rahman was dismissed by King Abdullah when, unhappy at being bypassed as crown prince in favor of Prince Nayef, he refused to declare allegiance to Nayef.
