Prince Nayef bin Abdullah (14 November 1914 – 12 October 1983) was the youngest son of King Abdullah I of Jordan and his second wife, Suzdil Khanum.
Nayef attended Victoria College in Cairo.
He became regent of Jordan on 20 July 1951, following the assassination of Abdullah, because his brother, King Talal, was reportedly suffering from poor health.
Nayef ruled in his older brother's stead until 6 September 1951, when Talal was judged fit to assume his royal duties.
