The Masjidkur Mosque is a mosque and archaeological site, located in Koyra Upazila, in the Khulna District of Bangladesh.^[1] The Kapotaksha River is beside the mosque and very close to the Sundarbans.

After the Partition of India in 1947, the mosque was discovered from before the area was full of forests and trees. Later on this excavation was discovered and the mosque below the ground was discovered. There was no inscription found during the discovery of the mosque, and there is no correct idea about its construction time. Masjidkur was named as the mosque was dug from the deep ground. Archaeologists believe that this mosque was most likely made during Khan Jahan Ali's regime as the area was under his rule.^[2]

Each wall of the mosque is approximately 2.1 metres (7 ft) wide. It was also constructed in the square that has an outer length of 16 metres (54 ft) and an inner length 12 metres (39 ft). There are three gates in front of the mosque and also four stone pillars made in the interior. There are nine domes in three rows, including walls and pillars.
