The First Macedonian War (214 BC – 205 BC) was fought by Philip V of Macedon against , Rome, allied (after 211 BC) with the Aetolian League and Attalus I of Pergamon, contemporaneously with the Second Punic War (218 – 201 BC) against Carthage. There were no decisive engagements, and the war ended in a stalemate.

During the war, Macedon attempted to gain control over parts of Illyria and Greece, but without success. It is commonly thought that these skirmishes in the east prevented Macedon from aiding the Carthaginian general Hannibal in the war with Rome. The "Peace of Phoenice", a treaty drawn up at Phoenice, in 205 BC, formally ended the war.
