Masjid Aqsab (Arabic: مسجد الأقصاب), also called Masjid al-Qasab, is a neighborhood and district of the Sarouja municipality of Damascus, Syria.

[1] The neighborhood was founded during the Mamluk era (14th century) as a suburb of the walled city of Damascus, bordering the Bab al-Salam gate to the south and contiguous with the al-Faradis neighborhood to the west.

[2] It was built around the Aqsab Mosque, after which the neighborhood was named.

The mosque purportedly contained the graves of seven Sahaba (companions of Muhammad).
