Public Gas Corporation of Greece A.E. commonly known for its Greek abbreviation DEPA is the natural gas supply company of Greece. The registered office of the company is based in Irakleio, Athens. It operates within the jurisdiction of the Ministry of Development.

In 2005, in order to liberalise the natural gas market, DESFA was created as a fully owned subsidiary to transport natural gas within Greece. Since then, DEPA sells gas to large consumers and to the gas supply companies. Natural gas is imported by pipelines from Bulgaria and Turkey and by liquefied natural gas at the Revithoussa LNG Terminal.
