Arunachal Pradesh /ˌɑːrəˌnɑːtʃəl prəˈdɛʃ/ (अरुणाचल प्रदेश) is one of the twenty-nine states of the Republic 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, Burma in the east and China in the north. Itanagar is the capital of the state. Arunachal Pradesh has territorial disputes with both the PRC and ROC due to its cultural, ethnic and geographic proximity to Tibet.
Arunachal Pradesh (अरुणाचल प्रदेश), 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. In recent times, large number of migrants from various parts of India and other lands have built extensive economic and cultural ties with the state's population.

The climate of Arunachal Pradesh varies with elevation. Areas that are at a very high elevation in the Upper Himalaya close to the Tibetan border have an alpine or tundra climate. Below the Upper Himalayas are the Middle Himalayas, where people experience a temperate climate. Areas at the sub-Himalayan and sea-level elevation generally experience humid, sub-tropical climate with hot summers and mild winters.
Arunachal Pradesh receives heavy rainfall of 2,000 to 4,100 millimetres (79 to 161 in) annually, most of it between May and September. The mountain slopes and hills are covered with alpine, temperate, and subtropical forests of dwarf rhododendron, oak, pine, maple, fir, and juniper; sal (Shorea robusta) and teak are the main economically valuable species.
