TheEuboean League (Ancient Greek:τὸ κοινὸν τῶν Εὐβοιέων,to koinon tōn Euboieōn^[1]) was a federal league (koinon) of the cities ofEuboea inancient Greece, extant from the 3rd century BC to the 2nd or 3rd century AD.

The League is first attested during the reign ofDemetrios Poliorketes (r. 294–288 BC), but is not mentioned again until from 194 BC on. Based on its coinage, it survived until well into theRoman Empire, possibly as late as the provincial reorganization underDiocletian (r. 284–305).^[2] It was a full federation (sympoliteia) ofcity-states, with its ownboule andecclesia, federal laws, common coinage (although the member cities continued to mint their own coins), and the right to grantproxenia. The League was headed by an official calledhegemon, whose name featured on federal coinage.^[2]
