Al-Mansur Ali ({{langx|ar|المنصور على}}, epithet: al-Malik al-Manṣūr Nūr ad-dīn ʾAlī ibn Aybak, Arabic: {{lang|ar|الملك المنصور نور الدين علي بن أيبك}}) (b. c. 1242) was the second of the Mamluk Sultans of Egypt in the Turkic, or Bahri, line. Some historians, however, consider Shajar al-Durr as the first of the Mamluk Sultans; thus, to them Al-Mansur Ali was the third Mamluk Sultan and not the second.(Shayal, p.115/vol.2.) He ruled from 1257 to 1259 after the assassination of his father Aybak during a turbulent period that witnessed the Mongols invasion of the Islamic world.
