Brahmanbaria[5] (bn|ব্রাহ্মণবাড়িয়া|Brāhmaṇabāṛiẏā)[6] is a city of Bangladesh and the capital of Brahmanbaria Sadar Upazila as well as Brahmanbaria District.

There are different views about how Brahmanbaria got its name. It is said that during the Sen dynasty, a shortage of Brahmins caused problems in worship. So, King Lakshman Sen brought some Brahmin families from Adisur's Kanyakunj to the area. Some of these families built homes in this place. Thus, the place was named Brahmanbaria because of the Brahmins' houses there.[9]
During the Indo-Pakistan War of 1971 for the liberation of Bangladesh, when Pakistan Army planners predicted India would launch its main attack in the east along the Akhaura–Brahmanbaria axis, it had no brigades available to cover this area, and Pakistan Army moved its 27th brigade from Mymensingh to Akhaura after retaining two battalions of 27th brigade at Mymensingh to form the 93rd Brigade to defend Mymensingh.[10] Pakistan Army's 93,000 troops unconditionally surrendered to the Indian Army and India's local ally Mukti Bahini on 16 December 1971. This day and event is commemorated as the Bijoy Dibos (bn|বিজয় দিবস) in Bangladesh and Vijay Diwas in India.[11]
