Sayyid Ali al-Akbar ibn al-Hasan (Arabic: سید علي الأكبر بن الحسن, romanized: Sayyid ʿAlī al-Akbar ibn al-Ḥasan) was a Sunni Muslim saint, and according to some historians of genealogy the second son of Imam Hasan al-Askari, the eleventh Imam in Shia Islam. His existence was hidden because of contemporary political conflicts with the political leadership of the Abbasids, reaching its peak at that time.
Sayyid Ali al-Akbar is venerated in Sunni and Shiite Islam as the patriarch of various Sufi Saints.
