The Council of State (Greek: Συμβούλιο της Επικρατείας) is the Supreme Administrative Court of Greece.

The Council executes its jurisdiction in Plenary Session or in six Chambers-Judicial Formations ( Α', Β', Γ', Δ', Ε' and ΣΤ' ).

It had advisory competence with respect to the draft decrees and administrative jurisdiction, issuing irrevocable decisions.

The administrative competence of the Council, as one of the three Big Bodies of the Public Administration (the other two are the Chamber of Accounts and the Hellenic Legal Council) is regulated by the article 95 of the Constitution of 1974/1985/2001 and consists in the elaboration of all the regulative decrees, namely of all the decrees that include impersonal (nor referring to a particular person) legal rules.

The Council includes in this limited category: The procedure is based on the principles of the "inquisitorial system" and of the initiative of the litigant.
