The Coalition Powers of the Flood War were the countries that opposed the Pan-Asian Allies during the Flood War (2026–2035). Former Allied state contributing to the coalition victory are not considered coalition states. The Coalition became involved during the Flood War either because they had already been invaded or were directly threatened with invasion by the Allies or because they were concerned that the Pan-Asian Allies would come to control the world. The anti-Turkish coalition at the start of the war, on July 22, 2026, consisted of India, Pashtunistan, Balochistan, and the Russian Federation. After 2032, the leaders of the Russian Federation, Japan, India, the Republic of China, Indonesia, and the United States of America, known as "The Big Six", held leadership of the coalition powers.
