Mahmudul Haque (Bangla: মাহমুদুল হক) was a contemporary novelist in Bangla literature. He was born in Barasat in West Bengal. His family moved to Dhaka after the partition in 1947. His novels deal with this pain of leaving one's home.
Mahmud gave up writing in 1982 after a number of acclaimed novels. Affectionately known as Botu Bhai and always seen as a lively figure in social gatherings, the rest of the time he was said to lead a solitary life.
