Chhetri, historically called Kshettriya or Kshetriya or Khas are Nepali speaking Rajputs of Khas community, some of whom trace their origin to migration from medieval India. Chhetri was a caste of administrators, governor and military elites in the medieval Khas Kingdom and Gorkha Kingdom. The nobility of the Gorkha Kingdom mainly originated from Chhetri families. They also had a strong presence in civil administration affairs. The bulk of prime ministers of Nepal before the democratization of Nepal belonged to this caste as a result of the old Gorkhali aristocracy. Gorkha-based aristocratic Chhetri families included the Pande dynasty, the Basnyat dynasty, the Kunwar family, and the Thapa dynasty,.

Khas tribe, popularly known as Khashya, according to the 2015 constitution of Nepal are an Indo-Aryan ethno-linguistic group native to the Himalayan region of the Indian subcontinent, in what is now the present-day South Asian country of Nepal, as well as the Indian states of Uttarakhand, Himachal Pradesh, West Bengal, Assam and Sikkim. Historically, Khas were the speakers of an ancient Khas language from the Indo-Aryan language family and the earliest recorded speakers of the Western Pahari languages. The large portion of the Indo-Aryan speakers throughout lower Himalayas were the Khas people. An intrusion of this tribe from the Western and Northwestern Himalayas into Central Himalayas is substantiated by the early linguistic evidences related to the Nepali language. They were also known as Parbatiyas/Parbates and are currently known as Paharis/Pahadis.. They were also referred to as Yartse in Tibet and are also known as Khasan by Bhotia people. The term Khas has now become obsolete, as the Khas people have adopted communal identities because of the negative stereotypes associated with the term Khas. In Nepal the native speaker of Nepali language are known as Khas people.
