The Shabandar Mosque (Arabic: مسجد الشابندر) is a historic 20th-century mosque located in al-Adhamiyah district of Baghdad, Iraq. The mosque was built by the Iraqi Arab Shabandar family, recognized as an important wealthy merchant and philanthropist family in Iraq that built several mosques with their wealth.

By the late Ottoman period, the Arab Shabandar family gained prominence in Iraq for being wealthy merchants and used their wealth to construct several mosques around Baghdad, including the Shabandar Mosque in al-Adhamiyya area, named after the family itself.

First built in 1902 by the philanthropist Mahmoud Ibrahim al-Shabandar, the mosque can accommodate at least 140 worshippers within its area of 300 square meters. Its summer prayer hall, or musalla, can accommodate at least 50 worshippers.

In 1906, Mahmoud Ibrahim al-Shabandar died, and he was buried in the garden of the mosque. The mosque also experienced a major renovation in 1938. Currently, the mosque does not have any endowments, but the funding for restoration or repairs is done by the current member of the Shabandar family, Sayyid Sa'eed Ibrahim al-Shabandar.

Other lesser known features of the mosque include a residential space for the needy, as well as a small private cemetery for the al-Shabandar family that is located in the mosque's garden. There is also a small basement underneath the mosque.
