The Siliguri Corridor, or Chicken's Neck, is a narrow stretch of land, located in the Indian state of West Bengal, that connects India's northeastern states to the rest of India, with the countries of Nepal and Bangladesh lying on either side of the corridor. The Kingdom of Bhutan lies on the northern side of the corridor. The Kingdom of Sikkim formerly lay on the northern side of the corridor, until its merger with India in 1975.
The city of Siliguri, in the state of West Bengal, is the major settlement in this area and the central node that connects Bhutan, Nepal, Bangladesh, Sikkim, Darjeeling hills, Northeast India and the rest of India.
