The Kori Creek (Gujarati: કોરી ખાડી, Urdu: کوری کریک) is a tidal creek and maritime Border dispute between the Kutch region of the Indian state of Gujarat and the Kachchhi region of the Pakistani province of Sindh. It is in the Rann of Kutch marshland east of the Sir Creek, which is disputed between India and Pakistan. It is a 96 km (60 mi) strip of water. The creek, which opens up into the Arabian Sea, divides the Kutch region of the Indian state of Gujarat with the Sindh province of Pakistan. The long-standing dispute hinges in the meaning of the words "from the mouth of Kori Creek to the top of Kori Creek, and from the top of Kori Creek eastward to a point on the line designated on the Western Terminus". From this point onwards, the boundary is fixed as defined by the Tribunal Award of 1968.
The creek itself is in the uninhabited marshlands. During the monsoon season between June and September, the creek floods its banks and envelops the low-lying salty mudflats around it. During the winter season, the area is home to flamingoes and other migratory birds.
