Tripura () is a state in northeastern India. The third-smallest state in the country, it covers 10,491.69 km2 (4,050.86 sq mi) and is bordered by Bangladesh to the north, south, and west, and the Indian states of Assam and Mizoram to the east. In 2011 the state had 3,671,032 residents, constituting 0.3% of the country's population.The area of modern Tripura — ruled for several centuries by the Manikya Dynasty — was part of an independent princely state under the protectorate of the British Empire. The independent Tripuri Kingdom (also known as Hill Tippera) joined the newly independent India in 1949. Tripura lies in a geographically isolated location in India, as only one major highway, National Highway 8, connects it with the rest of the country. Five mountain ranges — Hathai Kotor, Atharamura, Longtharai, Shakhan and Jampui Hills — run north to south, with intervening valleys; Agartala, the capital, is located on a plain to the west. The state has a tropical savanna climate, and receives seasonal heavy rains from the south west monsoon. Forests cover more than half of the area, in which bamboo and cane tracts are common. Tripura has the highest number of primate species found in any Indian state. Due to its geographical isolation, economic progress in the state is hindered. Poverty and unemployment continue to plague Tripura, which has a limited infrastructure. Most residents are involved in agriculture and allied activities, although the service sector is the largest contributor to the state's gross domestic product. According to the 2011 census, Tripura is one of the most literate states in India, with a literacy rate of 87.75%. Mainstream Indian cultural elements coexist with traditional practices of the ethnic groups, such as various dances to celebrate religious occasions, weddings and festivities; the use of locally crafted musical instruments and clothes; and the worship of regional deities. The sculptures at the archaeological sites Unakoti, Pilak and Devtamura provide historical evidence of artistic fusion between organised and indigenous religions.

West Tripura is an administrative district in the state of Tripura in India. The district headquarters are located at Agartala. As of 2012 it is the most populous district of Tripura (out of 8).
