Mujīr al-Dīn al-ʿUlaymī (Arabic: مجير الدين العليمي; 1456–1522), often simply Mujir al-Din, was a Jerusalemite qadi and historian whose principal work chronicled the history of Jerusalem and Hebron in the Middle Ages.

[5] He attended Islamic jurisprudence classes given by Kamal al-Din al-Maqdisi, a prominent Shafi'i scholar and qadi, at al-Madrasa as-Salahiyya, the most prestigious college in the city, and at Al-Aqsa Mosque compound.

[5] Extensive knowledge of Arabic, Hanbali jurisprudence, and Islamic theology, as well as his hailing from highly regarded and well-connected family, led to Mujir al-Din's procuring important posts as a public servant.

Though many books had been written by other Arab and Muslim authors on the virtues of Jerusalem, including about 30 composed during the Mamluk period alone, none of these set out to provide a comprehensive history of the city, making Mujir al-Din's work unique in both scope and design.

The first outlines the history of Jerusalem, and to a lesser degree Hebron, from the time of Adam to the end of the 13th century, incorporating both political developments and events of importance to Islamic and pre-Islamic monotheistic traditions.

The fourth part concerns itself with the history of Jerusalem during Mujir al-Din's own lifetime, under the rule of Mamluk Sultan Qait Bay.

[6] Composed in Jerusalem, Mujir al-Din alternates in referring to his place of residence as Filastin ("Palestine") and al-Ard al-Muqaddasa ("the Holy Land").

[4][13] A street in the Sheikh Jarrah neighborhood in East Jerusalem is named after him There is also a shrine in Nablus dedicated to the memory of Mujir Al-Din.
