Chalkidiki, also Halkidiki, Chalcidice or Chalkidike (Greek: Χαλκιδική, [xalciðiˈci]), is a peninsula in northern Greece, and one of the regional units of Greece. It is part of the region of Central Macedonia. The autonomous Mount Athos region is part of the peninsula, but not of the regional unit. The capital of Chalkidiki is the main town of Polygyros, located in the centre of the peninsula.
The Cholomontas mountains lie in the northcentral part of Chalkidiki. Chalkidiki consists of a large peninsula in the northwestern Aegean Sea, resembling a hand with three "fingers" (though in Greek these peninsulas are often referred to as "legs") – Pallene (now Kassandra), Sithonia, and Agion Oros (the ancient Acte), which contains Mount Athos and its monasteries. Chalkidiki borders on the regional unit of Thessaloniki to the north.
There are several summer resorts on the beaches of all three fingers where other minor towns and villages are located, such as at Yerakini (Gerakina Beach), Neos Marmaras (Porto Carras), Ouranoupolis, Nikiti, Psakoudia, Kallithea (Pallene/Pallini, Athos), Sani Resort and more.
The first Greek settlers in this area came from Chalcis and Eretria, cities in Euboea, around the 8th century BC who founded cities such as Mende, Toroni and Scione; a second wave came from Andros in the 6th century BC. The ancient city of Stageira was the birthplace of the great philosopher Aristotle.
In June 2003, at the holiday resort Porto Carras located in Neos Marmaras, Sithonia, European Union leaders presented the first draft of the European constitution. See History of the European Constitution for developments after this point.

Chalkidiki is popular summer tourist destination since late 1950's when people from Thessaloniki started spending their summer holidays at the coastal villages. At the beginning tourists rented rooms in the houses of the villagers. By the 1970s few tourists from Austria and Germany started to visit Chalkidiki more frequently. Since start of the big tourist boom in the 1980s the whole region is captured by tourism.
As of 2013 a revival of mining for gold and other minerals was underway with a number of concessions having been granted to Eldorado Gold of Canada. Gold was mined in the region in antiquity and environmental damage is present. Corruption, environmental damage, and only ephemeral economic benefits are feared.
The regional unit Chalkidiki is subdivided into five municipalities. These are (number as in the map in the infobox):
As a part of the 2011 Kallikratis government reform, the regional unit Chalkidiki was created out of the former prefecture Chalkidiki (Greek: Νομός Χαλκιδικής). The prefecture had the same territory as the present regional unit. At the same time, the municipalities were reorganised, according to the table below.
|New municipality||Old municipalities||Seat|
