Darjeeling is a Himalayan city in the Indian state of West Bengal. It is internationally renowned as a tourist destination, along with its tea industry and the Darjeeling Himalayan Railway, a UNESCO World Heritage Site. It is "hill town headquarters" of Darjeeling district with a partially autonomous status within the state of West Bengal. The town is located in the Mahabharat Range or Lesser Himalaya at an average elevation of 6,710 ft (2,050 m).

The development of the town dates back to the mid-19th century, when the British set up a sanatorium and a military depot. Subsequently, extensive tea plantation was done in the region, and tea growers developed distinctive hybrids of black tea and created new fermenting techniques. The resultant distinctive Darjeeling tea is internationally recognised and ranks among the most popular of the black teas. The Darjeeling Himalayan Railway connects the town with the plains and has one of the few steam locomotives still in service in India. Darjeeling also has several British-style public schools, which attract students from throughout India and neighbouring countries. The town, with its neighbouring town of Kalimpong, was a center for the demand of the Gorkhaland movement in the 1980s. The present movement for a separate state of Gorkhaland is also centered in Darjeeling town. In recent years, the town's fragile ecology has been threatened by a rising demand for environmental resources, stemming from growing tourist traffic and poorly planned urbanisation.
