Tin Bigha Corridor is a narrow strip of land located on the border between Patgram Upazila in Lalmonirhat, Bangladesh, and the Mekhliganj district in West Bengal, India, leased by India to Bangladesh in 1992 to provide access to the Dahagram-Angarpota enclave. This enclave, a large Bangladeshi territory surrounded by Indian land and separated from mainland Bangladesh by the Teesta River, relies heavily on the corridor for connectivity. The lease agreement allows residents of Dahagram-Angarpota to travel to and from the mainland, making the corridor vital for their daily lives and overall integration. In recent years, the Tin Bigha Corridor has gained attention as a tourist destination due to its geopolitical uniqueness, offering visitors a rare opportunity to witness the complexities of historical border arrangements and enclave life.
