The Peloponnese Region (Greek: ? , romanized: Periféria Peloponnísou, [peri'feria pelopo'nisu]) is a region in southern Greece. It borders Western Greece to the north and Attica to the north-east. The region has an area of about 15,490 square kilometres (5,980 square miles). It covers most of the Peloponnese peninsula, except for the northwestern subregions of Achaea and Elis which belong to Western Greece and a small portion of the Argolid peninsula that is part of Attica.
The Peloponnese Region was established in the 1987 administrative reform. With the 2011 Kallikratis plan, its powers and authority were redefined and extended. Along with the Western Greece and Ionian Islands regions, it is supervised by the Decentralized Administration of Peloponnese, Western Greece and the Ionian Islands based at Patras.
The Gross domestic product (GDP) of the region was 8.2 billion EUR in 2018, accounting for 4.5% of Greek economic output. GDP per capita adjusted for purchasing power was 17,400 EUR or 57% of the EU27 average in the same year. The GDP per employee was 68% of the EU average.
