Al-Shuaibiyah Mosque (Arabic: جَامِع الشُّعَيْبِيَّة, romanized: Jāmiʿ aš-Šuʿaybīyah) also known as al-Omari (Arabic: الْجَامِع الْعُمَرِي, romanized: al-Jāmiʿ al-ʿUmarī), al-Tuteh (Arabic: جَامِع التُّوتَة, romanized: Jāmiʿ at-Tūtah) and al-Atras mosque (Arabic: جَامِع الْأَتْرَاس, romanized: Jāmiʿ al-ʾAtrās), is the oldest mosque in Aleppo, Syria.

[1] After the fall of Aleppo to the Arabs under Abu Ubaidah ibn al Jarrah in 637, the Al-Shuaibiyah Mosque was built near the gate of Antioch, absorbing the ancient Roman triumphal arch which once marked the beginning of the decumanus.

The mosque was renovated by Abu 'l Hasan al-Ghadairi, a Shi'i, during the 10th century.

[2] In the 1150s, the Zengid ruler Nur ad-Din renovated and transformed it from a Shia mosque into a Shafi'i madrasa for Shaykh Shu'ayb.

[1] The rectangular short minaret reflects the earliest designs in the history of Islamic architecture.
