The Wars of the Delian League (477–449 BC) were a series of campaigns fought between the Delian League of Athens and her allies (and later subjects), and the Achaemenid Empire of Persia. These conflicts represent a continuation of the Greco-Persian Wars, after the Ionian Revolt and the first and second Persian invasions of Greece.

The Greek alliance, centred on Sparta and Athens, that had defeated the second Persian invasion had initially followed up this success by capturing the Persian garrisons of Sestos and Byzantium, both in Thrace, in 479 and 478 BC respectively. After the capture of Byzantium, the Spartans elected not to continue the war effort, and a new alliance, commonly known as the Delian League, was formed, with Athens very much the dominant power. Over the next 30 years, Athens would gradually assume a more hegemonic position over the league, which gradually evolved into the Athenian Empire.

Throughout the 470s BC, the Delian League campaigned in Thrace and the Aegean to remove the remaining Persian garrisons from the region, primarily under the command of the Athenian politician Cimon. In the early part of the next decade, Cimon began campaigning in Asia Minor, seeking to strengthen the Greek position there. At the Battle of the Eurymedon in Pamphylia, the Athenians and allied fleet achieved a stunning double victory, destroying a Persian fleet and then landing the ships' marines to attack and rout the Persian army. After this battle, the Persians took an essentially passive role in the conflict, anxious not to risk battle where possible.

Towards the end of the 460s BC, the Athenians took the ambitious decision to support a revolt in the Egyptian satrapy of the Persian Empire. Although the Greek task force achieved initial success, they were unable to capture the Persian garrison in Memphis, despite a three year long siege. The Persians then counter-attacked, and the Athenian force was itself besieged for 18 months, before being wiped out. This disaster, coupled with ongoing warfare in Greece, dissuaded the Athenians from resuming conflict with Persia. In 451 BC, a truce was agreed in Greece, and Cimon was able to lead an expedition to Cyprus. However, whilst besieging Kition Cimon died, and the Athenian force decided to withdraw, winning another double victory at the Battle of Salamis-in-Cyprus in order to extricate themselves. This campaign marked the end of hostilities between the Delian League and Persia, and some ancient historians claim that a peace treaty, the Peace of Callias, was agreed to cement the final end of the Greco-Persian Wars.
