Old Karimganj (IAST: Hindi: Purānī Karīmagaṃja; Urdu: {{Nastaliq|پرانی کریم گنج), also spelled as Old Kareemganj or simply Karimganj, is a residential neighborhood under the Civil Lines thana[1] zone of Gaya, Bihar, India, inhabited mostly by Muslims.[2] Forming the eastern wing of the larger Karimganj neighborhood, it shares its proximity with New Karimganj neighborhood to the west[3] and Jagdeo Nagar to the north. The locality is popular for serving the Karimganj Cemetery and infamous for its congested alleyways and poor drainage infrastructure.[4] [5]
Old Karimganj is the literal translation of Hindi-Urdu Purānī Karīmganj. The Hindi-Urdu purānī (Hindi: पुरानी; Urdu:) literally means "old" meanwhile the Arabic word karīm (Arabic: كَرِيم|) translates to "kind" or "noble" whereas the Middle Persian word ganj (Persian:) means "treasured place" or "neighborhood".
