The Great Rann of Kutch is a salt marsh in the Thar Desert in the Kutch District of Gujarat, India. It is about 7500 km2 (2900 sq miles) in area and is reputed to be one of the largest salt deserts in the world. This area has been inhabited by the Kutchi people.
The Great Rann of Kutch, along with the Little Rann of Kutch and the Banni grasslands on its southern edge, is situated in the district of Kutch and comprises some 30,000 square kilometres (10,000 sq mi) between the Gulf of Kutch and the mouth of the Indus River in southern Pakistan. The marsh can be accessed from the village of Kharaghoda in Surendranagar District. The Great Rann of Kutch together with the Little Rann of Kutch is called Rann of Kutch.
In India's summer monsoon, the flat desert of salty clay and mudflats, which average 15 meters above sea level, fills with standing water. In very wet years, the wetland extends from the Gulf of Kutch on the west through to the Gulf of Cambay on the east.
The area was a vast shallow of the Arabian Sea until continuing geological uplift closed off the connection with the sea, creating a vast lake that was still navigable during the time of Alexander the Great. The Ghaggar River, which presently empties into the desert of northern Rajasthan, formerly emptied into the Rann of Kutch, but the lower reaches of the river dried up as its upstream tributaries were captured by the Indus and Ganges thousands of years ago. Traces of the delta and its distributary channels on the northern boundary of the Rann of Kutch were documented by the Geological Survey of India in 2000.
The Luni River, which originates in Rajasthan, drains into the desert in the northeast corner of the Rann. Other rivers feeding into the marsh include the Rupen from the east and the West Banas River from the northeast. Nara Canal or Puran river which is a delta channel of Indus River empties during floods into Kori Creek located in the Great Rann of Kutch.
There are sandy islets of thorny scrub, forming a wildlife sanctuary and a breeding ground for some of the largest flocks of greater and lesser flamingos. Wildlife, including the Indian wild ass, shelter on islands of higher ground, called bets, during the flooding.
This is one of the hottest areas of India – with summer temperatures averaging and peaking at 49.5 °C. Winter temperatures reduce dramatically and can go below 0 °C (32 °F).
Although most of the marsh is in protected areas, the habitats are vulnerable to cattle grazing, firewood collection and salt extraction operations, all of which may involve transportation that disturbs wildlife. There are several wildlife sanctuaries and protected reserves on the Indian side in the Rann of Kutch region. From the city of Bhuj, various ecologically rich and wildlife conservation areas of the Kutch/Kachchh district can be visited such as Indian Wild Ass Sanctuary, Kutch Desert Wildlife Sanctuary, Narayan Sarovar Sanctuary, Kutch Bustard Sanctuary, Banni Grasslands Reserve and Chari-Dhand Wetland Conservation Reserve.
In India the northern boundary of the Greater Rann of Kutch forms the International Border between India and Pakistan, it is heavily patrolled by India's Border Security Force (BSF) and Indian Army conducts exercises here to acclimatize its troops to this harsh terrain.
This inhospitable salty lowland, rich in natural gas, was one scene of perennial border disputes between India and Pakistan that, in April 1965, contributed to the Indo-Pakistani War of 1965. Later the same year, Prime Minister of the United Kingdom Harold Wilson persuaded the combatants to end hostilities and establish a tribunal to resolve the dispute. A verdict was reached in 1968 which saw Pakistan getting 10% of its claim of 9,100 square kilometres (3,500 sq mi). 90% was awarded to India, although India claimed 100% of the region. Tensions spurted again in 1999 during the Atlantique incident.
The Indus river had been flowing in to Rann of Kutch area and Rann of Kutch used to be its catchment area forming part of its delta. Indus river branch called Koree river, shifted its course after an earthquake in 1819 isolating Rann of Kutch from its delta. Pakistan has constructed Left Bank Outfall Drain (LBOD) project to bypass the saline and polluted water which is not fit for agriculture use to reach sea via Rann of Kutch area without passing through the Indus delta. The 500 km long LBOD, begins from northern Ghotki district in Sindh province of Pakistan and joins Rann of Kutch in Badin district of Sindh. Rann of Kutch is joint water body of India and Pakistan. Water released by the LBOD is enhancing the flooding in India and contaminating the quality of water bodies which are source of water to salt farms spread over vast area. The LBOD water is planned to join the sea via disputed Sir Creek but LBOD water is entering Indian territory due to many breaches in its left bank caused by floods
The Government of Gujarat hosts an annual 3-month long festival during winter called the Rann Utsav where tourists can see the various sights of the Rann. For 2017, the festival of Rann started on 1 November 2017.
Rann Utsav gives visitors not only a chance to experience full moon on salt deserts but also get a taste of the local culture, cuisine and hospitality. Specially built local houses are also used to house tourists to give them a taste of local traditions Many adventure clubs and travel clubs organize expeditions.
Some women and young girls make their living by selling different types of embroidered cloths. The embroidery is of various styles such as Rabari, Ahir, Sindhi, Banni, Mutwa, Ari and Soof, some of which include mirror or bead inlays. 
J. P. Dutta's Bollywood film Refugee was shot in the Great Rann of Kutch along with other locations in the Kachchh district. It is said to have been inspired from the story by Keki N. Daruwalla based around the Great Rann of Kutch titled Love Across the Salt Desert.
Amitabh Bachchan in his promotions for Gujarat Tourism titled Khushboo Gujarat Ki has also extensively shot in the Rann of kutch. Several scenes in Salman Rushdie's Booker Prize winning novel Midnight's Children take place in the Rann of Kutch, including a scene where the protagonist faints from heat stroke in the Rann's brutal climate. Some scenes or song sequences in Indian films like Magadheera, D-Day, R... Rajkumar, Gori Tere Pyaar Mein, Goliyon Ki Raasleela Ram-Leela, Lagaan, The Good Road, Dookudu, Sarvam and Sarrainodu were shot in the area.
