Derbiga was a medieval Muslim city in Adal (present-day eastern Ethiopia). Located a few km northwest of Chinaksen in the Fafan zone Awbare of Somali Region.
French researcher Christian Bader recounts the fall of Derbiga according to tradition:
Reports specify it was the site of a large city encircled by walls, notable for its ancient mosque and the presence of Muslim burial sites. The construction employing dressed stones resembles that which is observed at other Islamic sites of Chercher and Ifat, dated between the 14th and 15th centuries.
Derbiga was discovered in 1931 by French archaeologists Père Azaïs and Roger Chambard with the assistance of the local Kabir. British researcher Richard Wilding later unearthed 14th century Chinese ceramics, suggesting that trade relations had been established between China and the eastern parts of the Horn of Africa.
