Uttarakhand (Hindi: Uttara + Khand i.e. North + Section or Segment), is a state located in the northern part of India. It was carved out of Himalayan and adjoining districts of Uttar Pradesh on 9 November 2000, becoming the 27th state of the Republic of India.

Uttarakhand has disputed borders with both Tibet (China) and Nepal to the north, and the east, and the internal boundaries borders with the Indian states of Himachal Pradesh and Uttar Pradesh in the west and south respectively. The region is traditionally referred to as Uttarakhand in Hindu scriptures and old literature, a term which derives from the Sanskrit for Northern Country or Section. With an area of 20,682 sq mi (53,566 km²).

In January 2007, the name of the state was officially changed from Uttaranchal, its interim name, to Uttarakhand. The provisional capital of Uttarakhand is Dehradun which is also a rail-head and the largest city in the region. The small hamlet of Gairsen has been mooted as the future capital owing to its geographic centrality but controversies and lack of resources have led Dehradun to remain provisional capital. The High Court of the state is in Nainital.

Recent developments in the region include initiatives by the state government to capitalise on handloom and handicrafts, the burgeoning tourist trade as well as tax incentives to lure high-tech industry to the state. The state also has big-dam projects, controversial and often criticised in India, such as the very large Tehri dam on the Bhagirathi-Bhilangana rivers, conceived in 1953 and about to reach completion. Uttarakhand is also well known as the birthplace of the Chipko environmental movement, and a myriad other social movements including the mass agitation in the 1990s that led to its formation.
