List of parliamentary constituencies of Greece

[1] Electoral constituencies account for 285 of the 300 parliamentary seats,[2] while the other 15 are elected on a national level through party-list proportional representation.

Each constituency, with the exception of those in Attica and Thessaloniki, corresponds to a single prefecture of Greece, even though these were abolished in 2010.

The number of seats in each constituency is calculated by first finding the national quota.

This is done by dividing the total number of legal residents in the country, as counted at the latest census, by 285 – the number of seats in the Parliament elected in constituencies;[3] using the 2021 census, the current quota is 34,089 residents per seat.

[4] In addition, Greece is a single 21-seat constituency of the European Parliament.
