Matlab Uttar (Bengali: মতলব উত্তর|Motlob Uttor|Matlab North) is an upazila of Chandpur District in the division of Chittagong, Bangladesh.[1] The former Matlab Upazila was bifurcated in 2000, creating Matlab Dakshin and Matlab Uttar upazilas.[1]
During the Mughal period, when the Lalar Hat Bazaar, located on the banks of the Dhanagoda River, a tributary of the Gumti, at the northern end of the present villages of Babu Para and Pail Para, was destroyed by river erosion, a market called Bairagir Hat at the northern end of the Kaladi village was founded by the Jamadar of Matlab. Jealous of this, the Zamindar of Faridpur increased his zamindari and established another market in his name in the western part south of the Bairagir Hat. After some time, both the markets became very competitive and Jamadar's haat bazaar became popularly known as Matlab rather than Bairagir Hat. The name Matlab was gazetted on 9 August 1918. Gazette No. 236. In 1900, the government divided the Chandpur circle and created the Matlab circle. As a result, the progress of police station with 22 unions started.
During the Bangladesh Liberation War of 1971, the area was under the control of Bengali freedom fighters. Whenever the Pakistan Army tried to enter the area, skirmishes would take place. A hospital was established for the wounded freedom fighters in the village of Nishchintapur. There were also mass graves in the village of Harina.
On 30 April 2000, Matlab Uttar Upazila, an archipelago surrounded by the Meghna-Dhanagoda river, started its journey as an independent upazila with 1 municipality and 13 unions (later 1 increase). Later on 5 September of the same year Matlab North started functioning as a newly created upazila. As the adjoining Matlab upazila is on the north side, this upazila was named Matlab Uttar.
