Tocharian languages A (blue), B (red) and C (green) in the Tarim Basin. Tarim oasis towns are given as listed in the Book of Han (c. 2nd century BC), with the areas of the squares proportional to population.

Tocharian B, also known as Kuchean or West Tocharian, was a Western member of the Tocharian branch of Indo-European languages, extinct from the ninth century. Once spoken in the Tarim Basin in Central Asia, Tocharian B shows an internal chronological development; three linguistic stages have been detected. The oldest stage is attested only in Kucha. There is also the middle ('classicalʼ), and the late stage.
