The Jama Masjid, also known as the Friday Mosque of Gulbarga, the Great Mosque of Gulbarga Fort, and formally as the Jamia Masjid - Qila-e-Hasham, is a Friday mosque located in Kalaburagi (formerly known as Gulbarga), in the state of Karnataka, India. The mosque is located within the Gulbarga Fort complex, in Kalaburagi.

In 2014, UNESCO placed the building on its "tentative list" to become a World Heritage Site, under the name Monuments and Forts of the Deccan Sultanate.

The mosque was built in 1367 by Bahmani Sultan Mohammed Shah I to commemorate the establishment of the capital in Gulbarga following the defeat Kapaya Nayaka of Warangal. The mosque was designed by a Persian architect, Rafi, and built within the Kalaburagi Fort complex. It is one of the earliest Friday mosques in South India.

The Kalaburagi Friday Mosque is notable for its divergence from typical mosque architecture of the time. The basic layout is similar to that of a courtyard mosque, except that the central courtyard is covered by sixty-three small domes. The mosque also lacks minarets, instead having four larger domes at each corner of the mosque. Three of the four outer walls are also open to sunlight, while the qibla is solid.
