Yafa'a (Arabic: يافع, romanized: Yāfiʿ) is an Arab tribe, geographical area, and a district of the Lahij Governorate, Yemen.

"[3] Yafa' has gone through a complex structuration of different tribal forms in the last several centuries.

In ancient times, the area was referred to as Dehsim or Saro Himyar.

The once ruling Qu'aiti dynasty of Hadramaut was Yafa'i in origin.

Yafa' was united with the rest of Arabia under the Rashidun Caliphate.
