Prince Nayef bin Abdullah (Arabic: الأمير نايف بن عبدالله, al-Amir Nayif ibn ʿAbd Allāh; 14 November 1914 – 12 October 1983)^{[citation needed]} was the younger son of King Abdullah I of Jordan, by his second wife, Suzdil Khanum. As a member of the Hashemite dynasty, the royal family of Jordan since 1921, Nayef was a 39th-generation direct descendant of Muhammad.

Nayef attended Victoria College in Alexandria. He underwent Military training in Turkey, being assigned as the honorary Aide-de-Camp of the Turkish President Ismet Inönü between April 1939 until shortly before the outbreak of World War II in September the same year.^[1] He became regent of Jordan on 20 July 1951, following the assassination of Abdullah, because his older half-brother King Talal was reportedly suffering from poor health. Nayef ruled in his brother's stead until 6 September 1951, when Talal was judged fit to assume his royal duties. Nayef died in Jordan on 12 October 1983.
