The Keygubad Mosque (Azerbaijani: Kеyqubаd Məscidi; Persian: مسجد کیقباد) is a historical former mosque, now in partial ruins, located on Gala turn in the Old City of Baku in Azerbaijan. The 14th century former mosque is on the south side of the mausoleum of Seyid Yahya Bakuvi.

The Keygubad Mosque forms part of the UNESCO World Heritage-listed Palace of the Shirvanshahs.

The precise history and function of the building is controversial. Historically, Keygubad mosque was a building of mosque-madrasa which was adjacent to Darvish tomb. Abbasgulu Bakikhanov wrote about Bakuvi on his teaching and worshipping in the mosque:

“His prayer room, his school and his grave is in there – in the mosque.”

Shirvanshah Keyqubad I was in power in 1317–48. According to prominent researcher, S. Ashurbeyli, Keyqubad was grandfather of Sheikh Ibrahim.

During 1918 events the mosque was burnt by Armenian troops.

In the southern part of the lower courtyard of the Shirvanshahs Palace, only the remains of the foundation and a few arches of Keygubad mosque are left.

The mosque consists of a rectangle worshipping hall and a corridor in front of it. Originally on the center of the hall, there used to be 4 columns to hold the dome. A portal was adjacent to the hall along with vestibule. On the southern wall of the hall there used to be a mihrab.

Together with the mausoleum and the Keygubad Mosque, the middle courtyard occupies a neutral position in the Shirvanshahs' palace complex due to its location.
