Polygono (Greek: Πολύγωνο pronounced [poˈli.ɣo.no]) is a neighbourhood of Athens, Greece.

In contrast to surrounding areas, it is not as densely populated, owing to a ban on the construction of multi-storey buildings.

The name of the area derives from a polygonal platform which once used to be set up for parades, opposite what are now the courthouses.

The area is also sometimes referred to as Gypareika (Greek: Γυπαρέικα), because Pavlos Gyparis, personal guard to Eleftherios Venizelos once owned a property there.

For this reason, the area is also sometimes known as "Eleftherios Venizelos' neighbourhood" and its central park is named after him.
