The City of Caral-Supe, or simply Caral, is an archaeological site in Peru where the remains of the main city of the Caral civilization are found. It is located in the Supe valley of Peru, near the current town of Caral, 182 kilometers north of Lima, 23 km from the coast and 350 metres above sea level. It is attributed an antiquity of 5,000 years and it is considered the oldest city in the Americas and one of the oldest in the world. No other site has been found with such a diversity of monumental buildings or different ceremonial and administrative functions in the Americas as early as Caral. It has been declared a Humanity Cultural Heritage site by UNESCO.

Caral–Supe was a complex Pre-Columbian era society that included as many as thirty major population centers in what is now the Caral region of north-central coastal Peru. The civilization flourished between the fourth and second millennia BC, with the formation of the first city generally dated to around 3500 BC, at Huaricanga, in the Fortaleza area. From 3100 BC onward that large-scale human settlement and communal construction become clearly apparent, which lasted until a period of decline around 1800 BC. Since the early 21st century, it has been recognized as the oldest-known civilization in the Americas, and as one of the six sites where civilization separately originated in the ancient world.
