Baba Adam's Mosque (, ) is a mosque situated in the village of Qadi Qasbah under Rampal Union of Bangladesh's Munshiganj District. It was constructed in 1483 A.D by Malik Kafur to function as a Jami mosque during the reign of Jalaluddin Fateh Shah. The tomb of Baba Adam Shahid, a 15th-century Muslim preacher, lies near the edifice.
According to the Arabic calligraphy inscription fixed aloft the central doorway in the east, the mosque was built in Rajab 888 A.H (August/September 1483 AD) during the reign of the Sultan of Bengal Jalaluddin Fateh Shah. It was constructed by Malik al-Muÿazzam Malik Kafur, one of the Sultan's officers. According to historian Ahmad Hasan Dani, Kafur was of Abyssinian origin. Now a protected monument under the Department of Archaeology, the mosque has been renovated and remains in a good state of preservation.
Split into two aisles and three bays, the rear of the wall on the west is displayed in three steps of which the middle part contains a multi-cusped ornamental arch-panel. The brick building is roofed over by six identical domes divided into two rows. Two freestanding slender octagonal-based black basalt pillars have chain and bell motifs. Stone pillars hold the pointed two-centred arches of the six domes.
All the entrances and mihrabs are recessed within rectangular frames. The south and north walls contain rectangular niches. The multi-domed mosque does not have a minaret. On both sides of the central doorway there are two multi-cusped rectangular panels. The arches are supported on faceted small pillars and decorated with a terracotta floral design. This type of facade decoration is also found in Shahzadpur Mosque (Sirajganj).
