Salweyn, also known as Salwine, is a proto-Somali archaeological site located in the Sanaag region of Somaliland.

[1] An excavation of one of these tumuli by Georges Révoil in 1881 uncovered a tomb, beside which were artefacts pointing to an ancient, advanced civilization.

The interred objects included pottery sherds from Samos, some well-crafted enamels, and a mask of Ancient Greek design.

[2] Additionally, close to the cairns are a number of rows of standing stones.

[3] Along with Macajilayn, Salweyn is also the only local site where specialized ancient disc-like monuments have been found.
