Arunachal Pradesh /ˌɑːrəˌnɑːtʃəl prəˈdɛʃ/ is one of the twenty-nine states of India. Located in northeast India, it holds the most north-eastern position among the states in the north-east region of India. Arunachal Pradesh borders the states of Assam and Nagaland to the south, and shares international borders with Bhutan in the west, Myanmar in the east and China in the north. Itanagar is the capital of the state. Arunachal Pradesh is claimed by the PRC and ROC since 1980's, though they occupied and withdrew after 1962 war.

A major part of the state, formerly called the North-East Frontier Agency, is disputed by China as the legality of the Simla Accord between Tibet and India is not recognized by it.. The state is seen to have major potential for hydropower development.

Arunachal Pradesh, whose name means Land of the Dawn-Lit Mountains in Sanskrit, is also known as the Orchid State of India or the Paradise of the Botanists. Geographically, it is the largest among the North-east Indian states commonly known as the Seven Sister States. As in other parts of Northeast India, the people native to the state trace their origins to the Tibeto-Burman people.
