Gilgit-Baltistan, formerly known as the Northern Areas, is a region administered by Pakistan as an administrative territory and consists of the northern portion of the larger Kashmir region, which has been the subject of a dispute between India and Pakistan since 1947 and between India and China since 1959. It borders Azad Kashmir to the south, the province of Khyber Pakhtunkhwa to the west, the Wakhan Corridor of Afghanistan to the north, the Xinjiang region of China to the east and northeast, and the Indian-administered union territories of Jammu and Kashmir and Ladakh to the southeast.

Kashmir is the northernmost geographical region of the Indian subcontinent. Until the mid-19th century, the term "Kashmir" denoted only the Kashmir Valley between the Great Himalayas and the Pir Panjal Range. Today, the term encompasses a larger area that includes the India-administered territories of Jammu and Kashmir and Ladakh, the Pakistan-administered territories of Azad Kashmir and Gilgit-Baltistan, and the Chinese-administered territories of Aksai Chin and the Trans-Karakoram Tract.
