Abasa is an ancient town in the northwestern Awdal region of Somaliland.
Abasa is situated about 25 km to the north of Borama as the crow flies on the road from Zeila. It is the most impressive of the ruins around Borama. A large town, it features numerous ruined structures stretching over a wide area. The buildings were built in a rectangular style, and the now ruined Abasa Mosque has large columns of two different types: cylindrical and cruciform. 14th to 16th century Islamic pottery and Chinese sherds have also been found here, which are believed to be relics from the Adal Sultanate's commercial activities.
