Zoskales (c. 100) was a king in the Horn of Africa, whose realm is thought to include Axum.
The Periplus of the Erythraean Sea has him as a ruler of africa Adulis, whose territory extends "from the Moschophagoi ['calf-eaters'] to the rest of Barbaria ... a stickler about his possessions and always holding out for getting more, but in other respects a fine person and well versed in reading and writing Greek".
At least as early as Henry Salt, some scholars, including Sergew Hable Sellassie and Y. M. Kobishchanov, have identified him with Za Haqala, who is listed in the King Lists of Ethiopia as having ruled for 13 years, and who ruled between Za Zalis and Za Dembalé.

Huntingford points out, on the other hand, that there is not enough information to be certain of this identification, and argues instead that Zoskales was a petty king whose power was limited to only Adulis.
