Papadoplaka (Greek: Παπαδόπλακα) is a natural reef islet off the southern coast of the Greek island of Crete in the Libyan Sea. The islet is in a bay between cape Lithino and cape Kefalas, at Kommos, and close to Gortyn which was the ancient capital of Crete. The name can be loosely translated as the priest's rock. It is administered within Heraklion regional unit.
There are a group of four islets in the bay including Papadoplaka (to the west), Megalonisi (with the lighthouse), Mikronisi (also known as Agios Pavlos), and Trafos.
Papadoplaka was more substantial in Minoan times, due to lower sea levels, and is likely to have offered safe harbour for ships in that part of the bay. J. W. Shaw believes that Papadoplaka is likely to have been linked with the coast via a partially submerged sandy shore. This would make a Minoan harbor at Kommos similar to the harbor at Amnisos.
