The term Himalayan states is used to group countries that straddle the Himalayas.

It primarily denotes Bhutan, China, India, Nepal, and Pakistan; some definitions also include Afghanistan and Myanmar.

[1][2] Two countries—Bhutan and Nepal—are located almost entirely within the mountain range, which also covers southern Tibet, the Indian Himalayan Region, and northern Pakistan.

[3] The inhabitants of this region are mostly speakers of the Indo-Aryan languages and the Tibeto-Burman languages.

[4] Some of the world's major transboundary rivers originate in the territory of the Himalayan states, including the Brahmaputra, the Ganges, the Indus, and the Irrawaddy.
