The Hellenic Parliament (; formally titled ), also known as the Parliament of the Hellenes, the Hellenic Bouleterion or Greek 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). It is a unicameral legislature of 300 members, elected for a four-year term.
