The president of Greece, officially the President of the Hellenic Republic, commonly referred to in Greek as the President of the Republic, is the head of state of Greece. The president is elected by the Hellenic Parliament; the role has been mainly ceremonial since the 1986 constitutional reform. The office was formally established by the Constitution of Greece in 1975, but has antecedents in the Second Hellenic Republic of 1924–1935 and the Greek junta in 1973–1974 which predated the transition to the current Third Hellenic Republic. The incumbent, since 13 March 2020, is Katerina Sakellaropoulou.

The Parliament of the Hellenes, commonly known as the Hellenic Parliament, is the unicameral legislature of Greece, located in the Old Royal Palace, overlooking Syntagma Square in Athens. The parliament is the supreme democratic institution that represents the citizens through an elected body of Members of Parliament (MPs).
