Abū Muḥammad al-Ḥasan ibn ʿAlī ibn al-Ḥasan ibn ʿAlī ibn ʿUmar al-Ashraf ibn ʿAlī Zayn al-ʿĀbidīn, better known as al-Ḥasan al-Uṭrūsh, was an Alid missionary of the Zaydi Shia sect who re-established Zaydi rule over the province of Tabaristan in northern Iran in 914, after fourteen years of Samanid rule. He ruled Tabaristan until his death under the regnal name of al-Nāṣir liʾl-Ḥaqq, and became known as al-Nāṣir al-Kabīr to distinguish him from his descendants who bore the same surname. He is still known and recognized as an imam among the Zaydis of Yemen.

Amol, also Romanized as Āmol and Amul, is a city in the Central District of Amol County, Mazandaran province, Iran, serving as capital of both the county and the district.
