Pagasae (Greek, Modern Παγασές) was a coastal city in ancient Magnesia (east central Greece), now a suburb of the modern city of Volos. It flourished in the 5th and 4th centuries BC. The only usable harbor in Thessaly was located on the Gulf of Pagasae, as it is still known, modern name being Pagasitikos. Pagasae was involved in the military campaigns of Philip II of Macedon.
