Keramidi (Greek: Κεραμίδι) is a village and a former community in Magnesia, Thessaly, Greece.

It is believed that there was a citadel and supply community at the sea level, dating back to the ancient Greece, which may have been called Kastanea, at the time of Homer.

There exist the remains of a massive-stone, fortified castle, and a legend that the treasures carried by the fleet were brought ashore and buried.

There, as early as the 17th century, the community of Keramidi grew isolated from the influence of the Turks during the 400-year occupation of Greece by the Ottoman Empire.

Also, there is the port and hamlet of Agrilia, where fisherman moor their boats now instead of the beach of Kamari.
