The Karchag Phangthangma (dkar-chag 'Phang-thang-ma) is one of three historically attested Tibetan imperial catalogues listing translations mainly of Sanskrit Buddhist texts translated to Tibetan. The title, in Tibetan dkar-chag 'phang-thang-ma, simply means the catalogue/index (karchag) from Phangthang (a place in Central Tibet).
