Greece is a peninsula; the seas are: Adriatic, Ionian, Aegean.
To the best of my knowledge, the major seas surrounding Greece are the Adriatic Sea in the west, the Mediterrenean Sea to the south, and the Aegian Sea to the east. There may be some regions of those seas that have been separately named, but I am unaware of them, if there are.

The Aegean Sea lies to the east of the mainland, the Ionian Sea to the west, the Cretan Sea and the Mediterranean Sea to the south.
