The Mediterranean Sea.
The body of land in Greece that is almost surrounded by water is called a peninsula. The most well-known example is the Peloponnese peninsula, which is connected to the mainland by the Isthmus of Corinth.
The body of water that almost cuts Greece in half is the Gulf of Corinth. It separates the Peloponnese peninsula from the rest of mainland Greece.
Greece is entirely in the Mediterranean Sea. The eastern coast of Greece is on a body of water of the Mediterranean Sea which is called Ionian Sea and separates Greece and Italy. The western coast of Greece is on a body of water of the Mediterranean Sea which is called Aegean Sea and which separates Greece and Turkey. The Greek coast on the Aegean Sea is longer than that on the Ionian Sea.
