Ibn Abī al‐Shukr (Arabic: ابن ابي الشكر; d. 1283 CE) was an Andalusī astronomer, astrologer and mathematician of the Islamic Golden Age. He belonged to the group of astronomers associated with the Maragheh observatory, most notably Nasir al-Din al-Tusi. In astronomy, Ibn Abi al-Shukr carried out a large‐scale project of systematic planetary observations, which led to the development of several new astronomical parameters.[1]
He died in Maragheh in modern-day Iran in June 1283 CE.[1]

- Risālat al‐Khaṭā wa‐ʾl‐īghūr: a chronological work on the Chinese and Uighur calendars, which was later translated from Arabic and Persian into Chinese.
- Three zijes:
- Tāj al‐azyāj wa‐ghunyat al‐muḥtāj (The crown of astronomical handbooks), also known as Al‐muṣaḥḥaḥ bi‐adwār al‐anwār maʿa al‐raṣad wa‐ʾl‐iʿtibār.

- Muqaddimāt tataʿallaq bi‐ḥarakāt al‐kawākib (Prolegomena on the motion of the stars): contains five geometric premises on the planetary motions in the Almagest.
Astrology
Ibn Abī al‐Shukr's astrological works were mainly devoted to horoscopes and planetary conjunctions used to tell the future.[1]
Mathematics
His works deal with geometry and trigonometry. His writings on trigonometry "contain certain original elements".[1]
