Pashtuns (Pashto: پښتانه Pax̌tānə; also spelled Pushtuns, Pakhtuns or Pukhtuns), also known as ethnic Afghans (Persian: افغان‎) or Pathans (Urdu: پٹھان, Hindi: पठान Paṭhān), are an Eastern Iranian ethnic group with populations primarily in Afghanistan and Pakistan. The Pashtuns are typically characterised by their usage of the Pashto language and practice of Pashtunwali, which is a traditional set of ethics guiding individual and communal conduct. Their origins are unclear but historians have come across references to various ancient peoples called Paktha (Pactyans) between the 2nd and the 1st millennium BC, who inhabited the region between the Hindu Kush and Indus River and may be the early ancestors of Pashtuns. Since the 3rd century AD and onward, they have been referred to by the ethnonym "Afghan".

Often characterised as a warrior and martial race, their history is spread amongst various countries of South, Central and Western Asia, centred around their traditional seat of power in medieval Afghanistan. During the Delhi Sultanate era, the Pashtun Lodi dynasty replaced the Turkic kingdoms as the ruling dynasty in the northern part of the Indian subcontinent. Other Pashtuns fought the Persian Empire and the Mughal Empire before obtaining an independent state in the early-18th century, which began with a successful revolution by the Mirwais Hotak followed by conquests by Ahmad Shah Durrani. Pashtuns played a vital role during the Great Game from the 19th century to the 20th century as they were caught between the imperialist designs of the British and Russian empires.
