Ashaghi Govhar Agha Mosque, Islamic mosque in Shusha, Azerbaijan.

Ashaghi Govhar Agha Mosque is a mosque in Shusha, in the Shusha District of Azerbaijan, with a rectangular prayer hall supported by octagonal stone columns. Two limestone minarets rise from the rear of the building, which also has a three-arched entrance veranda and adjoining rooms used for religious study.

The mosque is first recorded in Shusha's 1855 master plan, together with the adjoining madrasa. In 1874–1875 the complex was substantially rebuilt, and the new mosque was erected by architect Karbalayi Safikhan Karabakhi with the financial support of Govhar Agha, daughter of Ibrahim Khalil Khan, whose name it then took. It was badly damaged by Armenian armoured units' fire during the occupation of Shusha in 1992; restoration, funded by the Heydar Aliyev Foundation with Pasha Holding's support, was completed in 2024.

The mosque's name distinguishes it from the Yukhari Govhar Agha Mosque in the upper town; locals also call it the Lower Mosque or Small Mosque. Its minarets carry only the word Allah in a twisted-band geometric script, unlike the varied patterns on the upper mosque. The same motif appears on the minarets of the Barda Imamzade and Sheikh Safi tomb.

The main entrance is on the north-west side, aligned with the entrance of the madrasa opposite. The minarets stand at the corners of the rear, southern façade, which opens onto the small Qapan square; they are not on the main façade. The prayer hall measures 22.2 by 23.7 metres.

The limestone minarets are carved with repeated inscriptions of the word Allah, arranged so that the pattern shifts as you move around the building. This effect is most noticeable when you walk slowly around the rear of the structure.
