Porto Carras (Greek: Πόρτο Καρράς), known as Porto Carras Grand Resort, is one of northern Greece's largest and most famous hotels and holiday resorts. It is located on Sithonia, Chalkidiki peninsula in Macedonia, Greece. It is about 120 km away from Greece's second-biggest city, Thessaloniki.

Porto Carras has garnered a reputation as a popular destination particularly among Serbian tourists, who comprise as much as 90% of monthly visitor traffic. Its array of amenities, including luxurious hotels, a marina, a casino, and a golf course, coupled with its proximity to Serbia, have contributed to its appeal within this demographic.

Porto Carras was created by Yiannis Carras, a Greek businessman and ship-owner. Originally it was planned with the renowned architect Walter Gropius, but the construction works started posthumously in 1973. The project brought a revolution to Chalkidiki's tourism.

In April 2020, Porto Carras changed ownership and became a member of Ivan Savvidis' controlled Belterra Investments.

Porto Carras Grand Resort includes two major hotels, the 5-star Meliton and 4-star Sithonia as well as the bungalow style hotels Marina Village and Kalyva Mare. There are also 45,000 olive trees; basketball, football, tennis, and golf sports areas as well as a vineyard covering an area of 475,000 m². Porto Carras is home to the biggest private marina in northern Greece, having berths for 315 boats. It also contains restaurants, spa, interior and beach bars and a cinema theater.

The resort of Porto Carras is near the traditional village of Neos Marmaras; a tourist destination, busy during the summer period, with many restaurants, cafeterias and tourist shops.
