Highland East Cushitic, or Sidamic, is a branch of the Afroasiatic language family spoken in south-central Ethiopia. They are often grouped with Lowland East Cushitic, Dullay, and Yaaku as East Cushitic, but that group is not well defined and considered dubious.

The languages are:

• Burji (divergent)
• Sidamic proper
  • Sidamo
  • Gedeo
  • Hadiyya–Libido
  • Kambaata–Alaba.

Except for Burji, they are closely related. Hadiyya and Libido are especially close, as are Kambaata and Alaba. The most populous language is Sidama, with close to two million speakers.
