Sylhet Division (Sylheti: ꠍꠤꠟꠐ ꠛꠤꠜꠣꠉ, pronounced [sílɔʈ bibáɡ]; Bengali: সিলেট বিভাগ, pronounced [sileʈ bibʱaɡ] ) is a northeastern division of Bangladesh, renowned for its lush tea gardens, rolling hills and vibrant cultural heritage. Covering an area of approximately 12,298 square kilometres, it is bordered by the Indian states of Meghalaya, Assam and Tripura to the north, east and south respectively, while domestically it adjoins Chattogram to the southwest and Dhaka and Mymensingh to the west.
Prior to Partition in 1947, it included Karimganj subdivision (presently in Barak Valley, Assam, India). However, Karimganj (including the thanas of Badarpur, Patharkandi and Ratabari) was inexplicably severed from Sylhet by the Radcliffe Boundary Commission. According to Niharranjan Ray, it was partly due to a plea from a delegation led by Abdul Matlib Mazumdar.
