The '''Jaff''' people (also ''Jaaf'', ''Jaf'', ''Caf'' or جاف). are one of the biggest Kurdish tribes, if not the biggest,
native to the Zagros area, which is presently divided between Iran and Iraq.
The Jaff dialect is a branch of the Sorani language family. The region inhabited
by this tribe is south of Sanandaj all the way to Javanroud and also areas around
the city of Sulaimaniyah and Halabja in South of Iraqi Kurdistan.Once nomadic, they have more
recently settled into a predominantly agricultural way of life.
