Central Tibetan language, also known as Ü-Tsang dialect, Dbus Tibetan, or Ü Tibetan, is the most widely spoken Tibetic language and the basis of Standard Tibetan.

Dbus is the Wylie spelling of the name in Tibetan script, དབུས་, whereas Ü is the pronunciation of the same in Lhasa dialect, [wy˧˥˧ʔ] (or [y˧˥˧ʔ]). All of these names are frequently applied specifically to the prestige dialect of Lhasa.

There are many mutually intelligible Central Tibetan languages besides that of Lhasa, with particular diversity along the border and in Nepal:

Ethnologue reports that Walungge is highly intelligible with Thudam.

Glottolog reports these South-Western Tibetic languages as forming a separate subgroup of languages within Central Tibetan languages, but that Thudam is not a distinct variety. On the opposite, Glottolog does not classify Basum within Central Tibetan but leaves it unclassified within Tibetic languages.

Tournadre (2013) classifies Tseku with Khams.

Central Tibetan has 70% lexical similarity with Amdo Tibetan and 80% lexical similarity with Khams Tibetan.

Qu & Jing (2017), a comparative survey of Central Tibetan lects, documents the Lhasa, Shigatse, Gar, Sherpa, Basum, Gertse, and Nagqu varieties.
