Common Turkic, or Shaz Turkic, is a taxon in some classifications of the Turkic languages that includes all of them except the Oghuric languages.

Lars Johanson's proposal contains the following subgroups:[1][2] In that classification scheme, Common Turkic is opposed to the Oghuric languages (Lir-Turkic).

The Common Turkic languages are characterized by sound correspondences such as Common Turkic š versus Oghuric l and Common Turkic z versus Oghuric r. Siberian Turkic is split into a "Central Siberian Turkic" and "North Siberian Turkic" branch within the classification presented in Glottolog v4.8.

[3] In other classification schemes (such as those of Alexander Samoylovich and Nikolay Baskakov), the internal classification is different.
