Zoskales (Ancient Greek: Ζωσκάλης)[1] (c. 1st Century) was a King of Adulis located modern day Eritrea, many historians theorize he may have also been the one of the kings of the greater Kingdom of Aksum spanning both the modern day Tigray region of Northern Ethiopia and Eritrea.

In the Periplus of the Erythraean Sea, Zoskales is described as the only ruler of the region between Ptolemais Theron on the Sudanese coast and the rest of Barbaria.

George Hatke concludes that a realm as vast as Zoskales would likely have been based in the more fertile highlands where Aksum was situated rather than in Adulis.

This is because the coastal plain of Eritrea, which is around 40-60 km wide, is mostly unsuitable for agriculture to support a state as extensive as Zoskales realm.

[8] Zoskales likely maintained various residences across his realm and regularly stayed at each, a practice common among kings in history, such as medieval Ethiopian monarchs.
