The earliest recorded mention of Chalcis is in the Iliad, where it is mentioned in the same line as its rival Eretria.
It is also documented that the ships set for the Trojan War gathered at Aulis, the south bank of the strait nearby the city.
Chamber tombs at Trypa and Vromousa dated to the Mycenaean period were excavated by Papavasiliou in 1910.
In the 8th and 7th centuries BC, colonists from Chalcis founded thirty townships on the peninsula of Chalcidice and several important cities in Magna Graecia, such as Naxos, Rhegion and Cumae.
Its mineral produce, metal-work, purple and pottery not only found markets among these settlements, but were distributed over the Mediterranean in the ships of Corinth and Samos.

With the help of these allies, Chalcis engaged the rival league of its neighbour Eretria in the so-called Lelantine War, by which it acquired the best agricultural district of Euboea and became the chief city of the island.
Late in the 6th century BC, its prosperity was broken by a disastrous war with the Athenians, who expelled the ruling aristocracy and settled a cleruchy on the site.
Chalcis subsequently became a member of both the Delian Leagues.

Chalkis has had a Greco-Jewish presence since antiquity, which is sometimes claimed to have been continuous and to thus form Europe's oldest Jewish community, although there is no evidence of it through the early Middle Ages.

In the Hellenistic period, it gained importance as a fortress by which the Macedonian rulers controlled central Greece.
It was used by kings Antiochus III of Syria (192 BC) and Mithradates VI of Pontus (88 BC) as a base for invading Greece.

Under Roman rule, Chalcis retained a measure of commercial prosperity within the province of Achaea (the southern half of Greece).
