Uluru (Pitjantjatjara: Uluṟu), also known as Ayers Rock is a large sandstone rock formation in the southern part of the Northern Territory in central Australia. It lies 335 km (208 mi) south west of the nearest large town, Alice Springs, 450 km (280 mi) by road.

Uluru is sacred to the Pitjantjatjara Anangu, the Aboriginal people of the area. The area around the formation is home to an abundance of springs, waterholes, rock caves and ancient paintings. Uluru is listed as a UNESCO World Heritage Site. Uluru and Kata Tjuta, also known as the Olgas, are the two major features of the Uluṟu-Kata Tjuṯa National Park.

On 19 July 1873, the surveyor William Gosse sighted the landmark and named it Ayers Rock in honour of the then Chief Secretary of South Australia, Sir Henry Ayers. In 1993, a dual naming policy was adopted that allowed official names that consist of both the traditional Aboriginal name and the English name. On 15 December 1993, it was renamed "Ayers Rock / Uluru" and became the first official dual-named feature in the Northern Territory. The order of the dual names was officially reversed to "Uluru / Ayers Rock" on 6 November 2002 following a request from the Regional Tourism Association in Alice Springs.
