The Kel Adagh (var. Kel Adrar, Kel Adghagh, less commonly Kel Ifoghas) are a Tuareg confederation of clans (or "Drum-Groups") living in the region of the Adrar des Iforas highlands in Mali. The name comes from Tamasheq "Kel" ("those from/of") and "Adagh" ("Mountains"). In the modern era, not all Tuareg in the Adrar des Iforas are Kel Adagh, while some Kel Adagh are spread through northern Niger and southern Algeria, with populations in the Aïr Mountains, Tassili n'Ajjer, and the Hoggar Mountains. Most Kel Adagh derive from Noble and Warrior castes and their tributaries.
Noble Kel Adagh in Ifoghas include:
- Kel Afella (North) : tributaries of the Amenokal of Adagh.
- Kel Taghlit
- Kel Essouk (Religious caste tributary group)
- Kel Ouzzeyn
- Ifergoumessen
- Iriyaken
Tributaries include around forty tribes, the more notable of which are :
- Taghat Mellet ("Those of the white horse")
- Idnan
- Ibatanaten
