Yekçeşm Hüseyin Efendi (d. 1704) was an Ottoman scholar who was briefly Shaykh al-Islām.
At some point, he moved to Istanbul and became connected to the asitâne of Shaykh al-Islām Minkârizâde Yahya Efendi.
[1] Hüseyin was appointed müderris in various educational institutions over the years: Through the influence of Grand Vizier Köprülüzâde Mustafa Paşa, Hüseyin was appointed qadi of the Ottoman Army (Ordûy-u Hümâyûn) in 1689 and so participated in the recapture of Nish and Belgrade in 1690.
Amidst the turbulence, Sultan Mustafa II appointed Hüseyin Shaykh al-Islām of the Ottoman Empire on August 19 or 20.
Mustafa was deposed on August 22 and replaced by Ahmed III, who appointed a new Shaykh al-Islām.
