The Tarim mummies are a series of mummies discovered in the Tarim Basin in present-day Xinjiang, China, which date from 1800 BCE to the first centuries BCE, with a new group of individuals recently dated to between c. 2100 and 1700 BCE. The Tarim population to which the earliest mummies belonged was agropastoral, and they lived circa 2000 BCE in what was formerly a freshwater environment, which has now become desertified.

The Tocharians, or Tokharians, were speakers of Tocharian languages, Indo-European languages known from around 7,600 documents from around 400 to 1200 AD, found on the northern edge of the Tarim Basin . The name "Tocharian" was given to these languages in the early 20th century by scholars who identified their speakers with a people known in ancient Greek sources as the Tókharoi, who inhabited Bactria from the 2nd century BC. This identification is generally considered erroneous, but the name "Tocharian" remains the most common term for the languages and their speakers. Their actual ethnic name is unknown, although they may have referred to themselves as Agni, Kuči, and Krorän, or Agniya, Kuchiya as known from Sanskrit texts.
