Three Bigha Corridor) is a road or strip of land belonging to India on the West Bengal–Bangladesh border which, in September 2011, was leased to Bangladesh so the country could access its Dahagram–Angarpota enclave from the mainland.

According to the Indira Gandhi-Sheikh Mujibur Rahman treaty of 16 May 1974, India and Bangladesh were to hand over the sovereignty of the Tin Bigha Corridor (178 by 85 metres (584 ft × 279 ft)) and South Berubari (7.39 km2 (2.85 sq mi)) to each other, thereby allowing access to the Dahagram–Angarpota enclaves and the Indian enclaves adjacent to South Berubari.

India, however, could not transfer the Tin Bigha Corridor to Bangladesh as it required constitutional amendment which could not be done due to political reasons.
